Grow Type - Soil
Grow Stage - Vegetative
Bucket Size - Small pots
Lights - (2) 90w LED UFO and 4 75W FL grow light
Nutrients - None ( Just used Schultz plant food 3rd week after plants started turning yellow/very light green.
Medium - Espoma Organic Potting Mix Very light and i added some Bone&blood meal to it.
PH - 6.5
RH - 40% to 55%
Room Temperature -75 to 82
Room Square Footage - 8' x 8'

I'm not sure what happened but the plants were doing great and out of no where they started turning very light green/yellow in the middle of the stock up top were the new leaves were coming out. I just now added some plant food for the first time. Ive been doing 18/6 for lighting the LED UFO are 11 inches away from the plant.
2nd time growing some tips would be great. Thanks!

Is it possible to get some pics with the LED's off?

Sometimes when plants start a serious growth spurt it will be light yellow becasue the the Nitrogen level stored does not match the N level neededforthe growth. It usually corrects itself or growers add Nitrogen as a supplement. Pics without LED wouldbe very helpful is possible sir. :)
 
Yes sir. I see them now. :)
From what I can see andwhat I have read, I see a N problem. What is the NPK value of the shultz food? also is it granular? When a plant yellows from the bottom up its generally just a N use issue. But when it comes from the top down it could be an Iron or sulfur defiency. Heres a link that has way more information than I have. :)
PROBLEM solver pictoral. Ill also include a general leaf problem pic that may help.

Thank you for the link. I'l be checking it out. The plant food is 10-15-10 i'm using that and not the 20-20-20 i have because shultz has Manganese in it. its liquid in a bottle i used 14 drops of it in a 1 gallon spring water.

(After checking out that link i'm pretty sure it's Sulfur deficiency! I just gave them nuts and they got new water. Should i wait 3 days for adding salt or should i water them again?) I found out that the 20-20-20 food has sulfar in it! I will be using that next time!

I would give it about a week before making any other changes. Is this just regular potting soil you are using? Any possibility the soil has stayed wet the whole time? This could make it hard for the roots to uptake nutrients.

Not that i know of. I water the plants every 3 days and when i pick up the pots they are very light and dry.
After reading i guess i have been a little over watering when i do because a lot more then a couple of drops come out when i water. I will have to cut back on the water i give it.
 
hi, i was just about to mention the over watering, to me it looks like its just been over watered and the roots are starved of oxygen, in soil the plants should easily go 2 to 3 weeks in a small pot with no nutrients then when you transplant into a bigger pot they should happily go another 2 weeks without any nutrients at all.

plus you dont want to be feeding the plants that much this early on, you should be using about 1/4 of the stated dose, i would not be feeding any nutes while the plants are this young, they really dont need it as the soil has enough in it to easily go a few weeks in a small pot and another 2 weeks when transplanted to a bigger pot,

so for now id lay off the nutrients, let the roots recover as the over watering would of caused root rot, thats what i think is going on, the leaves look thick and bulging slightly so this is a clear sign of over watering, check the drain holes in the pot are not blocked, also they dont need much watering at this stage, just 1/4 to 1/2 a cup each time you water, you could possibly be watering only once a week, the plants need oxygen at the roots, so once thats sorted the problem will more than likely go away, the nutrients you are using should be enough to feed the plants all the need during veg but you will need to chance to a flowering nute when you flip to 12-12,

so for now id lay off the nutrients, they can go weeks in them small pots at least 2 or 3 weeks in a small pot then another 2 or 3 weeks when transplanted to a bigger pot, i think the problem is more than likely down to over watering, they will take a few days to recover and things might get worse over the next 24 to 48 hours but after that they should start to recover
 
Yup i think you are right. I bought a new electric PH tester also with a moister tester to go along with it. Hopefully this will help me out. I will give the plants 4 days and i will check them and make sure i dont over water them.. The drain is really good it has about 8 holes on the bottom
 
ok, keep us updated if their are anymore problems,

a good way of checking if it needs watering is to fill a pot of the same size with the same growing medium and leave this pot totally dry, then you have got something to compare it to, also a good way of checking if it needs watering is to carefully poke your fiingers down the pot about 2 inches then pull your fingers out, if they come out with moist soil then they dont need watering, with the plants been small it takes a good while to use the water up in the grow medium,

im pretty sure it will sort itself out, i did the exact same thing when i started growing, i cared for the plants to much but these plants are weeds and grow in dry climates, so they dont need much water, when they got bigger say 2 or 3ft then they will need watering more often depending on pot size, but while their small they dont take in much water so you tend to water more often,

any problems just give us a shout back, let us know how you get on and if the problem sorts itself out, im pretty confident it will do,
 
also i just had a look back at the pics and noticed you had the strip lights below the level of the canopy, this can cause light bleaching in your plants so might be best to raise the lights above the plants or turn them off and just go with the led's,
you could raise 2 of them and leave 2 off until the plants are bit bigger, your plants tend to bleach fairly quick, if you take a plant grown indoors then put it out in direct sunlight then it causes the leaves to bleach, this is why we train plants that are going out side by conditioning them, you put them out in the sun for an hour or 2 the first time then take them back in, then increase the time under the sun until the plants can cope with the extra light,

so at this stage you could get away with just usint the t5's or just the led's, what are the temps like at the canopy level, thats the best place to get a reading, but i think at this stage id have all lights above the plants,
 
oh i didn't know that would affect them. I turned them off until i can hang them up some how without hitting the LED lights. And after using the t5s the plant stopped growing up. Its about 40-50HUMID and 75-82 in temp.

UPDATE Got some new pics i re did the setup I have a bowl of water siting on a heating pad put the Humidity won't go past 45

the problem is the plants grow towards the light source, so having stronger lights below the plants means they will try and grow towards tne nearest light source, this may of caused you some problems but will be sorted now them lights are off,
humidity wont be causing that much of a problem at this stage as it will rise the bigger the plants get,

ive not used leds so not sure what type of light spectrum they give off but for veg i know the blue light is for veg and red light for flower, but leds i dont know nothing about so not sure how they are set up to produce the correct spectrum needed for veg and flower,

im pretty sure having them lights below plant level was possible what was causing you problems, if you could set it up so you had a t5 either end and in the middle of the leds then that can only help the plant grow quicker,

someone may jump in and help out with the leds but ive not used them at all so cant comment on them,
im pretty sure everything will sort itself out pretty soon, it just looked like light bleaching and with the light above and below the plants it was possible confusing them, i know side lighting is ok to use but not sure if its good to have a brighter light below the plant, so i think once you set the t5s above the plants then that can only improve the growth and help the plants grow much bigger,
 
The new lighting looks awesome! To get the humidity up you can hang a damp towel in there, be sure to change it out regularly though, and make sure it is a clean towel. Have the fan blowing on it. I also thought I would mention that I use worm castings and worm juice (this is the liquid that builds up at the bottom of their container) for pretty much all my plants house plants/succulents/garden...cannabis. They all seem to love it, and it never burns them.
