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!

Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 10008 months ago

PLEASE HELP ME, my frozen black cherry is drying, what could I do?It’s in the early third week of the flowering phase, but I don’t know some lower branches are drying out day by day, the first three photos shows what I mean, the last one is of the higher branches.
