Without knowing anything about the temps in your greenhouse, or anything about the LED wavelengths, it's kind of hard to guess at. If the space is cool, I'm guessing that you're not keeping the soil moist enough, because transpiration isn't happening as much at cool tems, and there is either a lockout of nutes, or the pH is high, because there isn't enough water in the soil, making the plant read it as "hot " soil.
Without knowing temps, light distance, etc.., it's only guessing.

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

Balcony Auto Gelato with Yellow and Brown LeavesI'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?

Late Flower Rapidly Yellowed LeavesThe yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.Week 19

Yellow sugar leavesI am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiary
