Hi guys,

So I’m week 6 in flower and I seem to get this fading/yellowing every time. I’m feeding like 700ppm 5 times daily in 5 gallon pots. I’m also adding 1.5-2 ml of liquid Kool Bloom to every res fill. Could this not be enough P or K? or a overkill of either? Runoff is almost right in line with what’s going in. I have them under 1000w DE with 1200 ppm’s of c02 so I know they can eat.

Thanks

can you check the RH and temps ?

what about your Ph ?

if run off is same as feed, maybe they don't eat at all

are you in pure coco or is there perlite or whatever mixed in ?

does it start suddenly or comes slowly ?

I would gently flush them with light solution, good Ph, then feed them again maybe with softer cocktail... how long they are supposed to flower ? it's maybe to late to do something about yield...

That color is high Mg and high N. No problem with either if there is enough Ca.

Hit a plant with a bit of gypsum 2 or 3 gr/liter water. Mix well and then apply the liquid.

Try one plant.

RH and temps are good 40-50RH, room temps 73-75. Lights are about 20” on that plant. I have others that are like 10” away from double ended and they look ok. I have a big AC. But the plant in question the light is about 20” above. I have only been using like 2-3ml of the micro so I’d be surprised if the N was doing it but maybe. I run calmag/Epsom salts once or twice a week.

I’m in pure coco, PH going in is 5.8-6.2. I bounce around. This is an 8-9 week strain so maybe it’s too late to do anything. The buds are getting fat as hell though. More than this strain usually does even when it’s picture perfect healthy.

It’s funny because last run I had a Stardawg strain that was all jacked up and the leaves where fading like crazy in week 3. But it ended up producing way nicer buds than usual.

not all genetics respond the same way about nuts

looked at the pictures it's like they get a fast forward flowering... so i guess it's only a little to much nuts for them, I don't know how you make your dosage but maybe you can try to slightly reduce the nuts concentration of... dunno 10%, during 2 days, and watch plants response

coco is fast medium, easy to correct nuts issue with little or big flush then giving them new solution, esay peasy

I've grown plants with half the doses of nuts, compare to what they write on the bottles... while some other strain can eat twice the dose... that's why I always start slowly and move up step by step... but this is my way nd i do hnd watering so this is easier to do, with automated watering and solution tank I don't know...
