What are you trying to say here?

I've used OF for all of my grows and never had any issues with overnuting. Its a great mix and i'd be suprised if thats what its from. How often are you watering and what does the soil feel like 1/2 in down when your watering?

Not trying to say anything.... I've already said it. I was the guy who suggested you might be letting the soil get too dry. I don't know what you're doing to the plant. I can't fix your plant for you.... no one can. It's up to you my fiend.

Looks like it might need a little more water... other than the leaves curling they look pretty healthy I'd say. Perhaps they are too close to the lights? A temp above 80 with close proximity to lights just may account for them drying.

My grow romm has temps in the mid 80's but I keep the humidity above 70% (usually 80%) so temps are nothing but a thang if you got humidity in check.

AND.... I'm 2 weeks into flower.

Update... mites are gone so far!!!! as for the other problems which seem to have got worse a bit since my last post I dug a little further and bought some soil ph testers and have found my soil is 5.7 ph on the 2 plants affected and my others range from 6.3-6.8? so I take it this is a nute lockout! ES I don't let the soil go dry for too long as the f&f OF seems to stay kind of moist for the most part and just the very top of the soil goes dry. are light is about 1 1/2 ft away at the moment as we are using a back up light due to a ballast going bad otherwise We use a 600 watt cooltube with a 400cfm fan cooling the light so I doubt the light is the culprit..

so it seems everything has been sorted out. it was a soil ph problem causing all nutes to locked out!! first to show was Nitrogen deff which looked like nuteburn it had got MUCH worse then pictured in my first post and growth slowed to a hault untill they recovered and started to grow again on the 22nd there still not a 100% well but things have taken off and are back on in full force!! the pic's below are 7 days of growth since the 2 plants bounced back!!!!!! they grew over 8' in a week btw!!!!

FFOF can cause Nute burn. Pure FFOF was awsome for my Blueberry grow. For Grapefruit-diesel it was too much. I diluted with peat moss and perlite almost 50-50 to get things going. Even such 50-50 mix is too much for seedlings. They need cooler soil. Also Organics CAN burn your crop, quick too. Whoever says not is out to luuch. Different strains of Marijuana have different affinities for hot soil. Its best to start very weak and condition to hotter soil. In your final transplant have two grades of soil, the hotter under the cooler. Generally......most people have nute burn issues as appose to deficiency issues. Also, In my opinion, flushing does not make nute burn worse, and as soil dries, the concentraation of nutes increases and could result in micronutrient lockup.
