Salve a tutti, non sono sicuro di aver fatto un ot...

I would remove some of those leaves for sure as they are quite busy but don't remove too many. Regarding the colouring, they are yellow because they are not accessing all the nutrients they need when they need them, this is because some nutrients can obtain be absorbed at certain pH levels otherwise they "lockout". Continue watering with nutes but raise your pH level between 6-6.5.this will help 🌱👍

Ph too low , in coco 5.8 and in soil 6.5 are the sweet spot. When the plants are in late flowering they are starting to yellowing due to the fact that they are less N available and they are eating less N and more pk so maybe when you starts to apply green sensation it increased the PK amount while the N amount was already low due to the Alga bloom. There is nothing you can do about it so don't cut the leaves. Generally burning tips means 2 things , either you have an overfeeding issue or a heat issue in the tent but from your temps looks like an over feeding , this could explain the lack of N if it was a flowering nutrients overfeeding : you can flush your medium to rince the excess nutrients in the soil.

Hello, Your buds look nice for a 1st grow. But looking at your diary the main thing I see would be to raise your ph if you're growing in soil...it may be that the nutrients are there but unavailable because of ph. I personally wouldn't remove any leaves that don't look completely damaged yet....sometimes if the problem is fixed they can get back some of their strength. The 1 plant may also have gotten less nutrients than the others if you mix up large batches of water...I learned the hard way to continually mix my jug while i water so that the nutrients don't separate and 1 plant get more than another. Good luck, happy flowering. ✌️

I looked at your diary and for me it looks like you are giving too much nutrients and/or wrong pH. What substrate are you growing in? Do you have a pH and Ec meters? Optimum pH for soil is 6-7 I believe and hydro 5.5-6.5. The way those leaf tips are curling upwards and yellowing/burning its a sign of nute burn and that overall yellowing looks like nitrogen deficiency but I believe you might have nitrogen or something else locked out 'cos you are giving too much nutrients and the salts build up in your soil. Best advice would be to flush with water with pH of ~6.5 and you should make good runoff. Measure pH and Ec of that runoff or just pour lots of water to flush almost everything out of the soil and after this give slighlty less nutes than you did before and check pH and adjust if necessary.
