Issues after switching to LED lights

[Rocket Soul]

Yea definitely Ill stick with the one bulb incandescent. I might put a few more LED bulbs on for heat if they just need a few degrees otherwise it’ll have to be the heat mat. Ive done flower runs with this heat mat underneath and its fine if the plants are raised off it a bit and have a fan down near the bottom of the tent. Which I like running air under canopy anyhow

All im pointing out is that you follow temp recs to achieve plant health; your plants look pretty good to me, always listen and check on the plants first, the thermometer is secondary, not a goal in itself

Thats a great point and I totally agree!

heres a breakdown of the feed im using lately. I use it like lucas formula more or less. With the extra calcium inputs I can adjust the N ratio of the Calnit w/o sacrificing calcium. Its basically a modified Jacks 321 formula. I use it for veg, flower, and to feed my mother plants.

They look over watered and the dead tips on the new growth are a zinc deficiency.
Your pH is probably to high causing the zinc deficiency and also your roots are saturated stopping uptake.
If they were mine ide let em dry right out and give em a good flush with pH at 5.7 and nutrients at normal ec.
As others have said if it's to cold they will slow right down thus using less water and becoming over watered.

drop your light intensity to around 60% they should perk up. thats first thing id change if you know your nutrient mix works well and dont have ph issues.
