yellowing is usually a N def, but if its only where the lights are, try rotating them.

Can't rotate the right side is higher than the other n then the tops would be touching the tube n I don't think it def I had all of them on the same feed in a tray together

If it is the plant getting the most light, it might be trying to grow faster than it's N uptake.

When I go into flower I back off the lights during stretch and about a week beyond.. or more.. More specifically I get lower watt lights, right up on top of them instead of just crank up the final flowering lights.

I've found backing off the lights keeps them lush and green, when bombarding them with light can zap them of a bit of green sometimes because they are hungry and eating quicker than the lower watt lights. Then once they go full flower I hit them full force and they never lose any color till the last day except here or there as plants will do.


That is just one train of thought.. if she is otherwise healthy, PH is good (for certain), then up her N intake a bit.. even if flower.. it wont matter.. it will help later IF that is the issue,.


Just one guy's thought process in your own research, good luck~!

Same as how you feed outdoor flowering plants twice as much as the same houseplants that are indoor. They get more light, they eat more, in general.
