QUESTION:
In pics the tops of the center plants have taken to turning yellow, very yellow. I think this is due to light burn, buuuut.......... The air cooled 600 is 9 inches from the tops. Unless this posses a MAJOR role in fucking up my crop I am not worried. So is this playing a role in fucking anything up ???

I run ebb and flo Techna Nutes. Rockwool and Hydroton. 3 15 min feeds a day. PH cool and nutes aren't low but maybe high. Started in flower 3 weeks age.

looks more like nutrient issue, i give my girls a bit of veg ferts in weeks 3 and 4 of flower, a little nitrogen burst, that may be your issue.

Are you using reverse osmosis water? It looks like a possible Magnesium or Nitrgen deficiency.

When you switched to flower did you flush system? Maybe lockout. I like to keep PH @ 5.8.

Not light burn at all.

Good Luck,

That looks like a N deficiency. I would start with a 1/4 solution of some Nitrix or something you prefer for some Nitrogen. Other then that the girls look fucking beautiful keep up the good work.

light burn it would look white on the leaves it looks like it might be clogged from getting nutes to the top i had that in my last grow so my tops wouldnt get big due to salt so you might want to just give it water to flush out and check the ph as well b4 doing so

No Ro water. No flush before flo. I flushed my res and plants yesterday and added 1/4 strength MagiCal and Awsome Blossom. When does color come back if that the case ?

My PH is cool Im confident in lack of nutes or light. I added a ounce af Magical to my 55 gal res last night after flushing and flipping the nutes. The plants are happy other than the yellowing.
