Light burn or something else?
jcbudstarted grow question 4 years ago
Hello Growers! Seeing some pretty bad rust spots on the top leaves, I'm thinking it could be light burn? I can't lower the intensity of my light since it's fixed (MH TS600W). Should I try to bend and tie down the top/main cola and hope it doesn't break? Tips appreciated!

Possible calcium deficiency. If you are already feeding some calmag then it could be a lockout issue . So you need to check your PH going in and going out . Check your run off PH, and if it's massively off you should feed extra volume of water(or your nute mix) at the correct PH until the run off is at an acceptable PH level . It doesn't have to be the same as what you put in . But you don't want it miles off as that can cause lockout issues. Hope this helps . She's coming along nicely š

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
Iām looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?
