Bump. I'm totally new to growing green man, but I hope you get this sorted. That's a big hit to take. I'm sure someone with some more experience will come along and lend some help.

Steve1214. With ffof you have a lot of nutes built into the soil. Add the Tri and it is easy to overfeed (I have done it). What is your water source. Is your water on the hard side. And how has the PH been running. Hang on someone will come along. Just give a little more info.

I've been going light on the nutrients. The water is spring water ph'd to 6.5. I don't think its nute burn....Thx for the reply.

Been growing a long time. New at AF's.
However from prior experience, when the buds develope to the point you're at,, I stop watching leaves.

Mission change (and all) I switch to trich developement.
Overall,, I think you're fine.

2 schools of thought;

a) buds draw from the fans in the end and get cast off.

b) energy is directed to bud production, sometimes negating older (larger) fan maintenance.

.. and a weird third one;
Ya don't smoke fans so who cares.

I play along number three.... but highly cogizant of the others in my grow.

Personally, I think you're looking good at this point.

Awesome reply my man. It's like the fan leaves did their part to get the plant to this point. Now its all about the buds. Thx much.

I agree that you're looking OK, Steve. Maybe a little early for the yellowing, but at this point you're probably best riding it out to the end. Looks like you've got plenty of fans left to get you through several more weeks. :smoke:

looks like magnesium deficiency to me... green veins yellowing leafs... bottom up...

use some epsom salt in your next waterin... 1 tsp per gallon

if you want fast-correction... use a sprayer to hit em with some phed 6.5 water with epsom salts... 1/8 tsp per quart or 1/2 tsp per gallon...

leave them out of the main light until they dry.... they may burn otherwise..
