Edges of some of the fan leaves are yellowing as well as some yellow dots on the leaves. Some of the tips also seem affected. overall the plant seems healthy but really worried about this. Posted some pictures above. What could this be?

Week 5

Leaves. Edges burnt

Hello! It can be leaf septoria, that is caused by a fungus or bacteria that attacks the plants in warm wet weather. It stars from the bottom leaves. If the yellow pots star to turn brown definitely is septoria. In this case you must remove the affected leaves. Or it can be a lack of nitrogen, that you need to keep in good high levels in the veg phase, but if there are no leaves falling, maybe that's not the problem cause in this case leaves turn yellow and fall for itself. Nitrogen is what makes leaves green and very important on photosynthesis. Nitrogen leves must be lowered at the begging of flowering stage, to not occur nitrogen toxicity. Be careful with over watering too, let soil dry, give them water for a couple days and they will recover.

You don't really need those fan leave cause they are taking light out to your lower branches. And i personally advise you change your light for a 400w so your tent doesn't hit up so much. Thats is why you have curl leaves. Hope it helps you. Happy growings 👌👌

your'e temps are to high which will cause you plants to use more water trying to keep cool ( edges curl in and become dry ). Growth slows at high temps which unless using co2 is bad !! It will also cause salt buildup in your'e medium as your'e plant isn't feeding it's concentrating on survival not growth. I would try to get temps to 25 and flush medium and measure your'e runoff PH / EC and that will let you know if there's any issues at roots. Hope this helps

PPM is good, lower the ec to 5.4 for a week to compensate the high ph level in the coco, lke Athos said, ph level needs to be between 5.5-6,0. This will develop build up of salts in your coco, which at time will be needed to flush out of the system. you can build up your feeding from 210 to 500 graduatly, when you see recovery in the new leaves, continue feeding at normal schematic The harm done to the leaves is irreversible, you will have to look at the younger leaves to see how she's feeling at the moment. I really hope she recovers soon, just send me a pm if i can help you out

I don’t see ph as being a major problem here. Plants can handle a fair amount of fluctuations in ph without too many issues as ph is what determines how easily the plant can absorb nutrients through the roots more acidic soils make nutes available faster more alkaline soils slower to me in what I believe was week 4 or 5 you had a larger dose age of your nutes it caused some burning and that’s what your seeing now. You seem to have adjusted your dose down and that’s a good thing and the newer growth seems to be much improved. I’d keep things where they are for now and watch for additional burning issues and maybe cut back further if the plant requires it

What you are seeing is pH related. 6.8 is the correct pH for growing in soil. For soil less (like coco) your pH range should be between 5.5 and 6.0, ideally 5.8. Most pH related issues, will give you weird leaf symptoms. Your nutes are not specifically formulated for coco, there could be some of this too, but I would start with correcting your pH, before changing anything else.

Don't worry about it yet , I don't know what the h2o2 is , sometimes when the plants are short and stocky the leaves rub as they grow and cause discolouration, keep an eye on new growth and pm me if it looks bad 👍
