Hi all. New to the forum here and fairly new to growing. I've got probably 6 grows under my belt. I have 3 girls in my 4×4 tent. My Runts has yellow tips on the leaves but the other 2 girls are fine. Overall the plant looks to be healthy otherwise. Im thinking this is a deficiency of some sort but only the Runtz seems to be showing the issue. What I've researched this could be light burn (but I don't think is the case). I'm trying to grow organically for the first time. I have the plants in 5 gal grow bags and they are on week 7 of veg. All 3 have been getting the same feedings and water schedule. I've only given them some foxfarm dry organic all purpose fert and adding FF Big Bloom during wstering. I've also been doing compost teas weekly using my local mushroom compost, worm castings, kelp, fish emulsion and molasses. I've also top dressed with a compost blend and worm castings. Soil is 50% coco, 25% used Ocean Forest and 25% FF Soil conditioner. Does anyone have an idea of what is causing this?
Yea I can't believe it would be nute burn. I know the symptom might suggest that, but these girls haven't been getting hit with a lot of nutes - mostly compost teas, a top dressing of worm castings and 2 feedings of FF Happy Frog dry all purpose fertilizer. Ive also been feeding the FF Big Bloom once per week. My soil is the fsrthest thing from being close to hot so im pretty sure it cant be that. And certainly no synthetic nutes. I know for a fact the tips were already yellow before the 2nd feeding of the AP on the 10th so it's hard to think it could be nute burn but I thought the chances of that happening growing organically was slim. And yea I'm flipping next weekend at 8 weeks. I'm shortening the light schedule in a few stages and by next Saturday they will go to 12/12.
the shortening of the light schedule is not needed i find it best to go straight from 18/6 to 12/12 but your plants are going to be huge good luck
you say.....certainly no synthetic nutes - but what do you think FF big bloom is? OF is hot out of the bag as is....you also used a soil conditioner as a primary base product. I think between that and mixing with a 50% coco mix it threw off the pH of your soil mix as well. You can def see overfeeding and it can be just as common and detrimental to overfeeding organics vs bottled nutes....the difference is in the rate of change where dry organic nutes take a while to break down before you see toxicity where bottled nutes exhibit their toxicity in a shorter amount of time due to the delivery mechanism. Next grow, use a 5 gallon of just OF and watch how the plant reacts....
FF Big Bloom is organic - OMRI listed. All 3 plants got the same feedings. If it is nute burn then it's only affecting the Runtz strain.
I find when I grow different strains all feed differently just watch them closely you will be alright sometimes keeping it simple works best
