Yellowing leaves three weeks into flower

Ok, my babies are not looking so good. Leaves are yellowing and dying off left and right. To me it looks like a definite nitrogen deficiency, but I may be wrong.

Since I thought it was a N deficiency, I gave them an extra 7.5mL of FloraMicro N-P-K 5-0-1 to help bump that up, but that was 2 1/2 days ago.

PPM is at 1720 and pH is right at about 5.8

Please help me!!!

Normal condition dude..the plants will use up all their N during flowering, you shouldn't be giving her any N right now!!!

ya dont give them more nutes anymore or u will hurt them just keep doing wat u were doing before

Ok, guys, I understand what you're saying, but this is only 21 out of 65 days of flower. If I was at say day 45-50, I wouldn't be worried at all about it. But they seriously are NOT looking good at all.

What are the roots like? It looks overnuted and/or in nute lock to me.

Roots are fine... they are a little dark, but so is the nutrient solution... as it is freshly mixed.

But your at 1720 ppm which is high for just nutes and some strains like heavy nutes and some don't. What strain you got there? Using the gh floro series I see! Me too!

Definitely give them N in bloom, seems like a common mistake to stop giving N in bloom, but it will hurt the yield. If you are worried about when to stop giving nuts, consult the feed chart of advanced nutrients. Definitely a nut deficiency, feed them a little more but be sure to flush the soil often.

I was at 2500ppm (on my meter) at this point and they took it like a champ (the f'd up leaves are from an early pH issue):

GH flora has a good bit of N in the micro. I use mine as directed on the label. You should be on 1-2-3 now. 5ml of grow, 10 ml of micro and 15 ml of bloom per gallon.

Then it's nute locked and you should flush with plain water for 2 or three days and maybe put in about 1tsp per gallon of H2O2 to help in the rocovery.

Well, for today at least, they just got 3mL/gallon of 35% H2o2. I just downed my second 24oz. Heineken and I'm done f'n with it for the night. We'll see how she looks tomorrow at 2:00pm when the lights come back on.

Until then, I would love to hear any and all suggestions!
