Looks like overfeeding/nutrient burn. I'd suspect potassium toxicity due the the yellow/burning tips. Thin new growth and ur large bloom feeding u just did. Dial it back fam. In most cases with cannabis less is more. Happy growing and stay lit fam.

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

Friends need your help! the leaves turn yellow at the seedling stage!
Friends, help me figure it out! First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom now I'll tell you how it was! after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0 drip irrigation works constantly! The temperature in the box is 23-25 C - humidity is 40-60% Inside, there is a fan on top that turns 360 degrees to blow the plants!

Leaves tips look burned
Any suggestion of how could make her look healthier? Tips look burnt and leave color is not great. Also my plant is very short, 25cm. I didn't feed her any nutrients so far, only water pH6.5. The soil (atami kilomix) was heavy fertilized with bat guano. Is she needing something?

New growth yellowing? Or am I paranoid
I'm really unsure if she's getting what she needs, New growth kind of shows a deficiency maybe? Using 4-4-4 and 2-8-4 Organic mix in the soil. I'm about to buy stuff to make a compost tea for them. She was healthy up to week 3, now showing this yellowing 🤷♂️ Thanks for help

Forbidden runtz excess or deficiency problems autoflower
BAD WEEK! need some help here guys.. Brown / rust spots started to appear on the tips and slowly started yellowing leaves. Im following the master advanced nutrients chart and watering 2 times a week. Last week feed was 20 litres R/O water 80ml bloom A 80ml bloom B 40ml of every additive on the chart 20ml cal meg 30ml phup PH adjusted 6.50 After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants. Yesterday i watered again but cut the nutes in half. 20 litres R/O water 40ml bloom A 40ml bloom B 20ml of every additive on the chart 20ml cal meg 20ml phup PH adjusted 6.50 I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else? since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me. Please any help will be appreciated
