SOIL Yellow leaves

[Redlin3m3]

Can anybody help me please as I'm in mid flower and I have 3 plants going yellow ?? I think it's too much lights so I raised them much .. 2x600w hps dual spectrum on 8x5 room.. rh50 26c temp .2 fans running on the pots . 2 fans on top of canopy . 1 feed 2 water . Ph 6.5 . Lights 70cm from plants ...

you could either bump up the dose of nutrients for 3 or 4 weeks, specially because this part of flowering needs high nutrients, or you could just feed more often, 1 feed 1 water or so. me personally like to feed more often

Dont you think it was caused by light ? It's just low nutes??

Get a Lux meter and you’ll know for sure if it’s the lights or not. They are inexpensive and a great tool, IMO.

its kinda all related more light= more photosynthesis= more nutrients needed. you did well raising the light in my opinion, give it a week or so and lower it once she has gained a bit more color or at least the yellowing stopped spreading.

I just ordered a lux meter and I'm waiting for it ... should I flush or not ??

flushing will make it worse, just feed more often and wait
