Much better pics! 1st pic, it can be a few things, from light burn to a number of deficiencies or toxicities..being im not sure of your medium, I can only guess. 2nd pic is surely nutrient burn..slight clawing and the odd yellowing can either be from the burn, from possibly spilling water on top of the leaves and the light caused a burn because of it, a possibility that she is rootbound or a combination of the 3. 3rd pic is the one I said possible magnesium def..it's a bit hard to tell, again because they do seem to have outgrown their space, I'd fix that first before feeding too much. If you have to..after transplanting, give the 3rd one a half a teaspoon epsom salt to the gallon of water. 4th one looks like a possible nitrogen deficiency, very slight albeit, and maybe magnesium as well, but again...could be a combo of being rootbound as well. All 4 pics seem to show very dry soil. I'd say transplant asap, give a healthy dose of ph'd water, and see how she looks in 3-4 days before next watering to see what can or should be added.
So I’ve search and searched but I think this is early stage of nitrogen deficiency. I looked at the thread on here but the early stage picture will not show up. I have a sealed grow room running two 300w mars LED lights. The soil is FFOF. Plants have been in it for about 3 1/2- 4 weeks now. I have been feeding them straight ph balance water between 6.3-6.8 PH level. I’m guessing the nitrogen is running out that’s been in the soil? I have fox farm nutrients but I’m fixing to transplant them into 3 gallon smart pots. If it’s nitrogen deficiency would the transplant to fresh soil take care of this or should I just start giving them 1/4 strength nutrients? The plant with the yellowing at the top is the only one like that. Thank you in advance.
