I could be wrong but it looks like zinc deficiency. Cold you get a run off pH and ppm?
Yes I can im planning on feeding them 2night when my lights turn back on. What could I add more of in my fox farm dirty dozen to give it more zinc?
@mwhite9829 Thank you for helping me out btw
@mwhite9829 I have another question. Looking at other peoples pics should my buds be way bigger then they are for it to be 4 weeks into flowering.
Mine are usually around that size at that time, some strains bigger. Bud development starts what seems slow then just starts plumping up, most growth in last couple weeks of flower. I'm pretty sure you'll probably have a lower ppm on the run off and need to increase nutrient amount. 4 weeks in flower at half dose usually isnt enough.
Ok i will give it a full dose next time I feed them nutes. I will just be feeding mollases and orca tonight. I appreciate your help man!
And the fox farm nutrients usually covers that but I would just go to higher dose , not exceeding the FF recommended amount for now.
Is the 6.5 PH , 1500 PPM you mention the runoff measurements?
@Mr. Grow It yes it is. What I find wierd is that its only 1 of them that looks like that the other 2 look fine.
@Alex Bermudez Really interesting how the yellowing is happening. This one is making me scratch my head a little. If it is Zinc deficiency like @mwhite9829 mentions, here is an article that gives tips on how to fix: https://www.growweedeasy.com/cannabis-plant-problems/zinc-deficiency The other leaves look fine; some may argue too dark of leaves. IMO you have enough nutrients in the medium, but maybe lower the pH for a short period of time to see if better uptake happens. When you water, do you have any runoff? If so, how much runoff and what do you do with it?
@Mr. Grow It yes I usually feed each plant about 1.5 gallons and get about 10% of run off. I usually wait until most of the water is done dropping before I set them back in the tent. Sometimes some water does stay in the catch trays for a few days. My ph run off is usually around 6.4-6.7
At the top you put 5 ml cal-mag, is that every feeding? If so the back of my head says overdose, especially since a lot of plant don't like heavy cal-mag in flower. @Mr. Grow It , calcium being immobile would affect the top first being youngest right? And could also lock out other nutrients I believe. Definitely got me a little stumped.
@mwhite9829 no I feed them cal mag whenever I feed them nutes. 5 ml per gallon
@mwhite9829 yeah we would see it top or sometimes mid leaves impacted first.
