Re: Watering. I used to totally saturate my plants, then let them dry out again before watering. When the plants were small, it might 4-5 days for the soil to dry out enough for the roots to breathe properly. This cycle takes too long.
I'm now being much more stingy with water. I always want to leave some part of the soil (roots) unsaturated, so I bottom water heavy and only give the top a small amount. Then I alternate and water the top heavy and don't give the bottom any water. I pretty much alternate feedings with just plain water too.
Early on (wks 0-4), I only feed through the bottom tray (500 ppm or so 10-15-10). I fill the tray and give the plant 5 minutes to draw up as much as it can. Then, I remove the plant and put in back in a dry tray. I'm only feeding little ones from the top if they clearly show they are starved.
I've been using a small plastic cup to hand water my plants so I can tell exactly what I add. I start by pouring one small cup in a circle around the plant. I'm trying to wet the area at the root tips which are typically under the tips of the outermost leaves. So, I add water right at the tips to start.
I do each plant. I wait a minute or two and repeat, this time moving outwards. I'll add just enough to wet the whole surface area between the tips and the edge of the pot. I add one more at a time at the outer edge, stopping at the first sign of runoff. While I wait, I clean up any plant debris and look carefully at my plants for changes. If there's an water left standing in the tray at the bottom after an hour, I drain it out. This tells me I added too much water.
Plants almost stop growing when their roots are under water. They grow rapidly when the wet-dry cycle happens over a couple of days.
During peak growth, plants process a lot of water and can suck the soil dry pretty fast. We have to learn to adapt to the changing needs.

I noticed that yesterday. I'm gonna give it awhile to suck up all the nutes and water. When watering I just make sure to get the root riot. I was watering til water came out the bottom so I could take ph levels of the drainage water. Then I got the 2 soil ph meters, so now I just wet the rr a little bit. This is so much more fun then working for someone else's grow lol. Thanks for the info, I know we all appreciate it.

I think most of the numbers you see in the forums are just fish stories. LED's work well, but are not magic. They save on electricity, but cost more up front. The nice thing is, they run cool, are very friendly and flexible to use and people are getting very potent cannabis from their grows. I just restarted growing cannabis after a 25 year break.
After 6 months, I'm harvesting "top shelf" qualify cannabis buds from my personal grow.
Here's what my small, personal grow setup looks like. I'm using 3 Mars Hydro 48x3w reflectors.
Here's one plant I grew in 0.8 ft2 (42 watts of lighting)
Hopefully, you'll get something that looks like this:
I ended up with 26g of fluffy, but very potent bud and 6g of prime sugar leaves from this one plant after drying.
I expect to harvest one of these every 10 days or so now that I've staggered my plant's start times.
If I can do it, so can you.
To harvest so often, roughly how many plants do you have going at the same time?
I'm currently running 6 plants, 1 - 2 weeks apart. I have a veg table with 4 T8s where I raise the clones to about 8-10" tall.
Everyone likes huge buds, but I've found it takes huge plants. The smaller buds can be just as potent, so I prune and train early and often before going into the flower cycle. I've got 3.5 strains, currently.
3 and a half strains?

They still look stressed from high nutes to me. It's hard to tell in the LED light pictures.
Spots can come from water droplets on the leaves during strong light.
If the spots grow, they are signs the plant lacks enough nutrients. Nute problems usually show on the oldest (bottom) leaves first.
Still, no cause for alarm. They should be pushing up another node within a day or two.

yep hard to see and yep could be cause by water when under the light
water magnifies the light

I think it was because before when I used the foliar spray and the light was only a few inches away, I'm now keeping it @ 2r inches. I also only use the foliar spray right before the lights go off. Thank you for the info once again!

Humboldt,
they look fine to me. I don't see any signs of heat stress or over feeding or watering issues. well done so far.

Thank you... I figured this morning with all the new green and growth that it cant be that bad lol.

I do the same thing for all 3 plants. Two out of three plants on the two lowest leaves, the oldest leaves, what is it and what causes it, do I need to flush?

Thank you for tbe reply. Do i move the lights further away to fix this issue? All new growth has been great.
