2nd grow, 5th week of flowering, seeking some help

[THC Onlyfans]

Hey guys, currently on day 35 of flowering and 2 of 3 plants seem to be running into some drooping and yellowing issues. Is this normal at this stage during flower? issue started around day 28 in flowering with CB dutch treat and Pure Power Plant. The yellowing are located in the fan leaves on the lower parts of the plant. Drooping is occuring in 80% of the leaves.
My OGK seems to be doing okay with just slight drooping but not much in terms of leaves discolouration.

Avg PH - 6.2
PPM - 660
Roughly 5-6 days between watering - 12 litres between 3 plants
Using green planet 3 part nutrients - Full strength
Day temp - 25-28c
Night temp 19-20c
Humidity 40-55%
2000w LED light (390w actual draw) - 17" from top of canopy
1000w LED light (180w actual draw) - 14" from top of canopy

Thanks!

It’s common for the plant to pull nutrients out of old fan leaves, moving it to where it really counts. Leaving a yellow or discoloured leaf behind. Looking good!

The dropping on the other hand, could be as simple as she’s thirsty, How’s the soil? Is the pot really light?

Has been drooping for a couple weeks now...I only watered when pot gets very light. Last watering was yesterday and leaves hasn't perked up.

Also, week 4 watering I added 4x recommended additive "liquid weight" which contains 7.5% sucrose, 7.5% dextrose, 7.5% Fructose. so I flushed with 6 litres of 6.2 PH water the following day.

Buds seem to be growing still though, should I just leave it and continue to monitor? just trying to catch any issues early while I can to avoid any major disasters.

Week four that happened with the nutrients eh? It should have bounced back from it since then. That does sound like a heavy dose of nutes. Maybe she’s still bouncing back from the flush?

You said 6 litres. What does that work out to in gallons, just over one in a half gallons of water. How big are those pots, 5 gal? It definitely should have been flushed with more then 1.5 gal. But it is what it is, the damage is already done. Definitely just let the soil dry out and closely monitor for any changes. Giving it a nice dry cycle might be good for it before feeding again.
