Growing Indoors
Foxfarm Organic Potting Mix
Growing in cabinet
Plants are in Veg. Stage Day 36
400w MH on 24-0
Good Airflow
Water Every 2-3 days, with tap water filtered through a Brita

I bought some foxfarm p.o.m. tomato and veg fert. (7-4-5) and I gave them each a 1/4 of the recomended amount for established indoor plants. I don't think that was my problem, because I was seeing the same symptoms before I fertilized. About 5 days ago I took them all and gave them a good watering until it drained out of the bottom and since then they have only got about 1qt each 3days later.

Most of the damage that can be seen in the pics is on the top leaves, but on some of the bottom leaves they also are getting little burn spots.

So heres the pics tell me what you guys think it could be, I don't think its overwatering, but I read that water stress thread and it made me wonder.

Thanks

are you adjusting the PH of your filtered water?

Ya, I'm gusing you have some Nute Lock. PH down your water (using PH down from your hydro store, or experiment with Vinegar if handy), and flush your plant to remove salt buildup. (I use "PH down" and use 2 drops for every gallon - gets the PH to 5.5-6)

Looks like:
Nitrogen Deficiencies:
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.
