PH problems
Mr_Weeds_Autosanswered grow question 5y ago
if you're going the organic way yes dolomite lime should do the trick, but I would suggest using GHE Ph Up, that way you water the plant until the runoff comes out between 6.0-6.5, this will give you faster results.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅Leaves. Edges burnt

Burnt? PH lock-out? too much Cal-mag??What do you think is wrong with this plant?
All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳4y ago
