I'm mid 7th week and one plant is looking super funky. Rest are yellowing a bit but I'm taking that as being normal, some brown on various leaves up top of the Holygrail but buds look good. This one plant just looks like shit. I also realized throughout flower I've been UNDERFEEDING a bit but as of last two the ppm's have been bumped up to 11-1200 mark.
The last 3 pics are of Holygrail 69 only one that was topped and the one that's yellowing a bunch with some dry brown blotches towards middle and top (not that it matters for this just for recognizing in other pics) and other 3 are sour d's.
Setup is 1000w HPS 440cfm exhaust, passive intake, oscillTing fan. Daytime temps 75-78° night 63-66°. RH 45-35%. Soil is 50:50 FFHF and coarse perlite in 5gal smart pots. Feeding GH micro, bloom, snow storm ultra, crystal burst, floranectar and added a bit of CalMag past 2 feedings. Both sativa dominant have printout from breeders flowering on both is 60,65-70 days. Just don't want too many leaves to die too soon.
haha.. that looks like a picture straight from my textbook... so i'd lean more towards Potassium (K) deficiency rather than Phosphorus (P) Also i love the shameless bud shot on the third picture lol. Edit: compliment
add more feed containing the above or could it also be a ph problem cos im having slight similar problems too
Well since ai have 3 weeks left (2 with food) I started using MOAB it's like 52-35 some crazy PK numbers. Worked well first week so we'll see. Buds all look great smells delicious, leaves just look shitty. But that's to be expected a bit
With crystal burst in your mix I would think your potassium levels are solid. Maybe check your meter in some pH 4 AND pH 7 calibration buffer to make sure you meter is right. Another cause of potassium def is too much calcium or sodium which. what's your ppm's out of the faucet? Do you have a water softener? You can look up your city's "water quality report" on google.
