That's actually the beginning of a potassium deficiency.... but the question is why are you getting it at this point! Make sure your pH pen is calibrated if you have one.... this type of deficiency is often related to a pH that is not in the proper range... yours seems to be (best range is 6.0-6.5 and 6.2, which you say you have, is ideal)... Beyond that, you should add some PK boost .... KoolBloom liquid is something I use and has an NPK of 0-10-10... so that ought to do it. Good luck!

Why DP's leaves are so small?Hi guys! Do you have any idea why Durban Poison is growing so slowly? I am suspicious I might have hurt her during the transplantation. She has 3 pairs of leaves and she is healthy green, but her leaves are very small...strange from a sativa. She has the same age as my Durga Mata

Plant with strange "leaves schema"A plant (1st veg week) grown from old RQS AMG seed has a strange "leaves schema" very different from the other plants: leaves don't grow in couple but in a messy way with no order. Is it something going wrong or this plant is healthy like that?

Magnesium deficiency? How to cure it?Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance

Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

2 of the very bottom leaves yellowed and fell, and 2 other started to show yellow parts, It seems to have stopped now. Wondering if it's due to the high heat and very dry air, or if it's nutrient related. Thanks!
