Hi @Whodey420! My bet is that your soil has developed salts buildup / old nutrients accumulation, and the rootzone is now unable to manage nutrient intakes anymore. This could be related to your feeding schedule, I see you add maaaany nutrients but without measuring the final EC? that would explain everything. In this situation I would flush the medium for a few days with only plain pH'd water, and I would buy an EC-meter to ensure that the feedings aren't too hot. Remember it's always easier to fix a slight deficiency than to recover from a slight toxicity, that's why you must measure your EC and slowly add nutrients step by step only if the plant is asking for more. Hope this will help, keep us updated and happy growing! 👊

Leaf tips are yellowing or browning and getting crusty and they go little on claw like when bad burn. I'd say your feeding schedule could be cut down little bit. Those yellowing spots looks like some kind of salt build up. Give plain water couple watering and then cut down your nutes by 1/3 and go from there. 👍

Are you measuring the EC/PPM? With so little information it is hard to tell. The spots look like calcium deficiency or lockout. Do they appear on the top leaves or the bottom ones? If top, then it's calcium

Have a look at my leaves that have turned yellow and red. I've search online and can't seem to find a similar picture. Is this normal due to late flowering in some plants? Is this a nute problem? If I add the needed nutes, will this clear up? What's going on?Week 8

Tried everything - Red spots almost everywhere. Turn from red to orange/yellow. Fungus?Getting very frustrated with these speckles. Iv tried decreasing Cal Mend and B-52. Improving air flow. Cleaning the tent head to toe and the res. Iv tried using UC roots. Im really not sure what's going on and IDK what to try to fix it. Grow was going so well. This sucks.

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower?
max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout?

Are the red spots genetically caused, or is this a deficiency ? Day 26 close up Picturethe plant is now at day 26 and is now 60cm tall and is so bushy that it fills the whole tent. The pre-flowering is in progress. I have a reddish discolouration on the uppermost leaves and in the places of the pre-flowering. But the leaves look top.
