Trekkystarted grow question 6y ago

Hi everyone, I'm a new member of the team, I started an indoor grow 1 month ago. For the past 2 weeks, I've been noticing a strange yellowing of the first leaves of an autoflowering plant, but I don't understand the problem since I'm using a fertilized substrate and coffee grounds for nitrogen.

Reduce nutes for a bit, may be lockout. Stop foliar spraying leaves, or dry them off when anything drips on them. they are solar panels. roots absorb water and nutrients, not leaves. Those products are made to pry you from your money. (excluding pesticides when you have a pest, not preventative) you don't fertilize? the soil will only provide enough for only so long without it. if it worsens, go ahead and provide more.. N is a good bet. if you think you've bombed it with N lately, back off for a bit and see how it reacts.

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

Jaunissement ou brûlure ?Yellowing or burns on 2 leaves on a plant! Could this be due to the lamp being too close? 40 cm With SpectraPanelX160 X 4 lamps and 2 SpectraBulbX60 with the same 60-watt COBs. The manufacturer Floraled advises me to keep it at 40 cm with the 120° lenses. What do you think? Thanks a lot!

Manchas amarillas I've noticed some yellow spots on the lower leaves, and I'm not quite sure what it is. The first pistils just appeared, and I don't know if that has anything to do with it. Could you help me? Deficiency? Over-fertilization? Have they been burned by direct sunlight? Is this normal? Thanks!
