pics with light on are to show led growth in 2 weeks under 360 watts



look at the plant in the middle
my thoughts are S from over watering could that be why leaf tips are pointing down and leaves curled up? Or could it be a mix of over fert or heat stress (tips curling down) + over watering

temps as low as 70 to as high at 87 usually not over 81 tho

3 in the back are gdp, middle left is kens gdp, middle is purple ak47, middle right and front sides are purple diesel, middle front is a unhappy kens gdp that is going outside as soon as planting season starts.

my personal opinion is i over watered and its preventing sulphur uptake but looking for other views.

Yo,
It seems like in the photo the tops have a bit of a sickly green color(maybe its just the flash of your camera). If the younger(upper) blades have that nice fold like yours do, its not really an over watering issue, imo.

The mid section spotting is probably a nutrient burn. The containers are a bit large too, which only promotes more root growth.

Those lights are great. Correct me if I'm wrong, but it was my understanding that it is important to promote root growth first.

Do you allow the grow medium to completely dry before watering again? If so how do you tell if the pots are dry?

judge by weight. also stick my finger in the soil. I allow it to get pretty damn dry so that roots will seek new water but the problem is i started them out in 2 gal containers so sometimes the soil does not dry on the bottom where the roots havent reached yet...well the roots probably are everywhere now but they were not at first. I water all of them the same just this plant isnt liking everything life as much as the others.

i dunno im not really worried i just foliar fed it some N and S solution it should recover in a few days.

Thorough watering and thorough drying of the root medium will help even distribution of roots from top to bottom, and help the pots to conformly dry.
