Leaf changed color and spotting, help!

Kappakrusadestarted grow question 4 years ago

Any idea what I need to do to fix this? I think I over fed and then I recently did and RO flush. Then I fed it calcium herkley and harvest recharge in a little general organics bloom.

Hard to say from the picture but your diary give away the problem, in this case your plant is suffering from Calcium (Ca) Toxicity - Leaves develop Yellowish-Brown spots, tips and margins begin to suffer chlorosis, while leaves remain dark green in color. Lower the CaMg+ to about 0.2-0.5ml/l (consider even stop using it after a few lower dosage irrigations) since your "Bio-Bloom" fertilizer has enough Calcium additives and it is usually needed only when the plant shows deficiencies. Calcium is a micro-nutrient and needed in very small amounts (sometimes the calcium in the soil is enough for the whole grow). Hope this helps! Good luck and happy growing :)

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Deficiency or light stress?I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?

Droopy leaves, curling at tips, and now brown/yellow splotches on leaves in DWC. Not sure what the issue is Unfortunately, I can only write so much here, but I have a lot more details in my grow diary. The droopiness started about 3-4 days ago, but now has started showing deficiencies in the leaves, and plants seem stunted on height. Day 19 since sprout.
