Nute burn?
Realtree8858started grow question 8 months ago
Is this nute burn or something else? Growing in 5 gallon fabrics pots with soil / the bottom has super soil. Plants are 100 days old.

It is in fact nutrient burn, probably nitrogen. The tell tale sign is the browning of the tips without turning yellow first/around the burned tip.

It's classic nutrient burn 100% Done it before. Looks exactly the same.

my best guess would actually be a potassium deficiency. since the rest of the plant looks healthy. it starts on older leaves and works its way up.

Deficiency?Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmkLeaves. Edges burnt

Crispy dry margins on the upper leaves. Please see detailed pics through week 5 of flowering. Pics from different days are available.The younger plant was showing what I thought to be P and K deficiencies on the leaves. Growth stopped too. Increased its nutrient amount 3 days ago (bloom-grow-acti). Since then I observed some bud growth but the problem on the upper leaves continue. Any ideas?Week 5
