Hey 420Mag growers,

So i have a few issues i would like to share with you guys to diagnose my issues that could be BIG or small, here is a brief idea of whats going on.

I am growing in soil with a few little amendments such as a little bit of "bat guano" "Fish, blood and bone meal" with added perlite and vermiculite, they are about week 4 of flowering and i have "2 OG kush" + "1 BigBang" in a 5x5 tent under a 400w HPS bulb, i tend to water every 2 - 3 days depending on how much the plant takes up, once with pure RO water then with nutes days later. I use RO water and let it sit for a few days at room temp with a constant ph of around 6.5 give or take without being adjusted, for my nutrients i am using "Plant Magic oldtimers grow + bloom" with a little PK booster and Cal+mag of course.

2 of my plants are doing really great big and healthy but one OG kush and slightly the other but not so much have issues and are showing numerious problems, I cant pinpoint what the issue is i have come the the conclusion its something going on with the root system but this could be false so any help would be greatly appricated and looked into carefully.

Here are a few photos of my issues:

It's not nute burn, the tips are all still green. Early flowers need more potassium and phosphorus. If they progress from dark blotch to dried up yellow/browm its phosphorus. If it's whitish like it looks there it could be any one of the micro nutrients. How's your Ph levels in the soil? And it's hard to tell in the lighting what colour the leaves are. Search for a picture deficiency tutorial, they are very effective in diagnosing symptoms. Hope you get it resolved, if the leaves become dried up you can snip them off...cheers
 
Mind you looking closer, it looks like some very minor nute burn in the past but the majority of the leaf tips and ridges are still green or in recovery. Just a small addition. Good luck!
 
Hey Drivishe and Snidrajsed,

Drivishe i dont think it is nutrient burn as hardly any of the leaf tips are burnt just one or two leafs.
Snidrajsed i think your right and somehow i am getting nutrient lock out but i dont understand since i am using organic nutrients "Plant Magic old timers" and PH shouldnt really play a role but this could be wrong, i need to know how to correct this what do i need to test or get correct cause now one of my other plants are showing simliar signs and i believe my yeild is going to be drastically effective if i dont do something soon!

To begin with when i realised another plant had the same problems i thought it was some sort of pest or disease but it makes sence for it to be a nutrient lockout because i havent really been checking the PH as i thought it was irrelivent because of its organic nature, however i did check my last watering with nutrients and it was low around 4.5 so i upped it to 6.5 and fed each 30 liter air pots with about 6 liters of water.

Thanks guys
 
It's easier for you to find the minor various symptoms you may have and compare them to that picture guide
