Hello.
This is my second grow.
The first one i finished around 3 months ago with a similar setup. I have a 120W led DIY panel witch worked fine on around 5 grows so far (not mine). On that light i added around 14 11W lights with warm white and 4 cold white 15W lights.
After i switched to flowering i only kept 2 blue lights and the rest were normal warm white lights.
The problem i have now is that the leaves started getting brown first on the tips. i thought it was too much nutrients. Then i watered it with only water ( i try to keep the PH in the 6-6,5 range with the digital ph meter but sometimes when i add nutrients i works strange so i check with the ph papers). After that the edges started getting brown. Then i saw it was too little "P". After i added nutrients to the wather the problem stopped.
Then i had a cycle with watering and nutrients and that ended well. But now 5 weeks and 5 days after the flowering started the leaves began to change color rapidly. Getting brown spots, turning brown ad dying.
I turned off 10 lights now to rule out light burn.
I started looking for bugs but i dont see anything.
What should i do.
Thank you for the help in advance
