Hey guys.
I'm in the vegging stage with diamond dream og in coco grow and the leaves have been showing these symptoms for the past week. I flushed them, and only fed them water and cal-mag (I think its a calcium deficiency) but they show no signs of improvement. Somebody please help!!
You have to know the PH and is the coco a complete soil if it is it should have all the nutrients the plants need for at least a month before you need to start heavy ferts. If you don't know the PH you are guessing and adding calmag won't help, get a PH test kit they aren't as accurate as a professional test but they will keep you in an acceptable range.Quote:

My ph level when I mix with cal-mag is 5.8-5.9 and the coco is a soiless medium.

Nutes, skipped a couple waters and actually added more air flow. She's doing great now. All the info I have to offer. Good luck !!:stoned:
I have the exact same problem, My grow is outdoors and all was fine intil today. I been watering all weekend with an overdose of superbloom and today I added a dose of superthrive. We also had a huge down pour so maybe they will look better this week. These were spindly autoflower transplants
That's pretty low it should be close to 6.5. Don't guess you can do more harm than good.
Some times leaves yellowing from the bottom signal oxygen deficiency in the soil. This happens when the soil (or coco) stays wet for too long. The plant can not take in oxygen from the soil. Let the soil dry out, try to loosen up the soil to introduce some air.
