Leaves with yellow spots
towelliestarted grow question 2 years ago
We have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Well, for a soil grow, a pH of 5.5 is far too acidic to start off with here... your ideal pH is 6.2-6.3 but anywhere between 6.0 and 6.5 (some would say 6.8) is good. I think you've got the start of a calcium deficiency or some OTHER deficiency and that's probably the result of your pH issues... calcium and magnesium cannot be absorbed if the pH is lower than 6.0, phosphorus requires 6.2 minimum, so to get this lady back on track, I would focus on pH...
Good luck!

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.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

What do you think the problem could be?There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

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.
