Yellow stains on bottom leaves (indoor grow)
Belzebubstarted grow question 6y ago
On day 25 yellow stains have appeared on the bottom leaves of two plants (critical 2.0). We don't know from what these stains are coming.
On one of these plants, some leaves have also started to develop white dots. Spiders maybe ?
Thank you.

Hey, buddy! 👋
This is an early stage of manganese deficiency! It was triggered by the too alkaline pH of your soil!
Solution:
- Flush your substrate first thing! Because this deficiency could have been caused by an excess of iron (which could be the case) and we need to get rid of all the unknowns in your soil! Set the pH to 6.3 and add nutrients according to your feeding schedule for the flowering stage! I see she's already in pre-flower and will be blooming soon, bro!
Good luck, buddy! 😇✊

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, whI'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

Slow growth yellow leaf edges what to do?Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Yellow streaks between leaf veinsAll three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?
