esko42started grow question 4 years ago
The picture with the tag(unknown deficiency) shows an unknown deficiency on some leaves. The tips and edges of some leaves are dry and crispy and some have spots resembling a calcium deficiency. We have had a few hot days 35 degrees+. Just ordered a calmag sup.

This would be due to a lack of moisture. The big giveaway would the crispy, dry appearance that shows up on leaf tips first, then progresses to the entire leaf. This often happens during hot, dry weather when moisture evaporates before the plant can absorb it through the roots.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Wrong pH for three weeksI realized I was feeding my plant tap water with a pH of 8-8,5 for a good three weeks. I just flushed my autoflowers, three times the amount of soil with water corrected to 6-6.5. Will that solve this issue I was having (nutes lockout I think)? Did I fix my soil pH by doing this?

Leaves slowly dying. Nute burn? Heat Burn? Overwatering?Leaves are slowly dying on two of my plants. Starting to appear higher up at the tip. What could it be? PH, nute burn, too much light, overwatered? I may have overfed: 0,75mL Power Roots and Alga grow every two days since they were 10. Is it really bad?
