Can anyone help?

HI I'm hoping that someone can help... I have 5 clones of the same plant and it seems that everytime I get them to flowering they start to turn a light green. It makes me think they need something but then the tips are slightly burnt so I'm not sure. Also a couple of the fan leaves begin to develop brown spots. I'm thinking a new fertilizer maybe but right now I'm using Fox farm liguid bloom with some tiger bloom and I use Thrive alive for veg. Any ideas?

Good morning Kisses
Sounds and looks to me like your not feeding them enough in veg.
Thrive Alive is not a fertilizer, give your plants a shot of nitrogen 1/2 strength for a couple more feedings and you should see the yellowing stop.
Hope this helps ya some.

Looks like they need some extra nitrogen.They appear pale green.

I know I must be missing something here, it that leave still attached to a plant? All I am seeing is fair looking plants shedding a leaf, maybe its these old eyes. VV

i'm going with nitrogen.
