Hi there! If your plant tends to be lime green or pale all over, even though the leaves appear healthy without stripes or spots, then it's a Nitrogen deficiency. If your leaves are clawed and have a deep dark green, then it's a Nitrogen abuse/burn. If your issue only concerns the highest leaves, then it could be a light-burn. If your issue only concerns the new growth, then it could be an Iron deficiency. From what I see in your last pictures, this looks more like a deficiency. In every scenario, wrong pH can be involved. I'd recommend to re-calibrate your tools and double check your pH. Hope this helps, keep us up-to-date so we can help you in parameters adjustments, and happy growing!

First of all, get an EC/PPM meter, it will go a long way in taking out the guess work.
Second, yellowing tips are not a sign of nutrient deficiency, period. It's always a sign of nutrient overdose

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Main stem snappedLST gone wrong. Main stem snapped after the last LST session, must have happened a while after adjusting the ties. Taped the damaged area. Will it recover? How long would it take?
It looked like only 25% of the stem was holding it together. The area got red/brownish.

No Color Loss - Week 7 Flower?Sup Gromies!
Got a quickie for yall. Usually around week 5 of flowing the plants tend to fade in color as the buds use up the nutes from the leaves. Well this AMS AK-47 XTRM is holding its color and tomorrow is the start of week 7! The strain only has an 8 week flower. Thoughts?
