Browning leaves

SmokinTees420started grow question 5 days ago

My leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle

Leaves. Color - Dark-brown

As the others said it’s probably a ph issue. But it looks that the problem is about calcium it can’t uptake it so you get a deficiency. So probably your calcium and magnesium volume is very low so try to look over your ph, and correct the ph in the medium by watering and watering and watering until the ph that runs out the pot is in the right range 5.5-6,5 in coco and 6-7 ph in soil. Ur run off has to be something in between these rates to be a healthy plant! If it’s not in these rates your plant won’t be able to drink the nutes that’s in ur medium. It just drink the water and evaporate it trough the leaves and ur humidity RISE A LOT! so to keep a good environment you need to keep the plants healthy and in the right ph range. Good luck sorry for so much information I hope you know what I mean. If you don’t just DM and I’ll try to explain more deeply 😊 good luck my friend

I think you are dealing with a pH issue here. The twisting of the leaf as well as the browning like that makes be think that. I would first: You said it’s 6.2pH. If that is true I do not think you would be having any issue. I would recalibrate your probe that you are using. Second: Once you confirm the probe is accurate, adjust your next watering to the correct pH and run a bunch through your soil till you get about 20-30% run off out the bottom. Do a run off watering like that for two waterings. This should help correct any with pH.

Ph problem, check your pen or start measuring it. Calcium would be possible too, but all look of plants screams ph , humidity and wind issues. Maybe some wrinkle was influenced by low humidity and heavy light, but its still things to sort out ...

Hello- I noticed in the other week of your diary entries that some water was splashed on the leaves in your pictures. I kind of suspect that spots are the result of water droplets concentrating the light like a magnifying glass and burning the leaf. Be careful of water droplets on leaves. The best way to judge light is by a PAR map. There are some cheap bluetooth meters out there that connect to your phone and allow you to create a clear map of the PPFD conditions in your tent. This is what you should try to do if you want to maximize DLI or even just target something. At this stage of their life they really don't need more than 400 ppfd. This will change a little based on your light cycle.
