Leaf discoloration and curling
Jake13255started grow question 4 years ago
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.

If curling up and getting dry it is nute burn. Make sure you are getting run off each feed about 20 percent of what you put in. If not you may have build up from salts causing burn and causing your ph to spike down,thus causing nute lock out . Also test ph of run off to be sure.

I actually believe nutrients are not the issue here, but the light schedule and climate!
24/7 light on your plants may sound great but in reality it reduces yield and may even kill your plant before you get to harvest! Plants use the night time to burn energy (sugars and proteins) made by Photosynthesis and stored in the leaves to grow. The climate problem is the temperature in your grow space, 17-18 degrees Celsius might be manageable during late flowering but in vegetative growth the plant needs a temperature range of at least 22-28 degrees Celsius (28 being the max unless you use supplemental Co2). Humidity levels seems fine and as mentioned before me here keep your fertilizing solution at 1/4 strength at this point of growth and slowly increase as the plant grows, never go with recommended amounts straight away because it causes toxicities pretty easily!
Hope this helps! Good luck and happy growing :)

I only fed them like a very little squirt one time and not again since. It’s been watered a few times since feeding.

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. Haven't watered for a day, but I don't think its a overwatering problem.

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 1000a year ago

EC too high and leaf yellowEC 1.45 and some yellow leaf… I adjusted the soup by adding water to it and the new leaves seem to be pretty ok. Otherwise, all other parameters are good. It’s odd bc I followed instructions of the brand (Platinium Hydroponics) and the EC lvl is still kinda high. Suggestions?

Yellow/gold spots on top fan leaves in bloom phaseI noticed a couple of the top fan leaves have got some small yellow/gold spots developing. I've been using the same Bloom feed for this plant as my 3 Bears Smile which is 8 days further along. I'm wondering if that might be causing the problem and how I fix it.
