First try

Week 4 Day 22 of flowering New week started and I topped my reservoir with 15l of fresh water and nutes and I adjusted my nutes slightly. Less N and little bit more PK and now Ec 2.5 and pH 6.3 and the girls seem to love it. Daytime temperature is 25-28 'cos the added led is old and adds heat to the tent and also humidity is lower now so I'm thinking about raising the humidity little bit. I've been trying to foliar feeding them once day still and I think they like it a lot. Day 24 of flowering Tucked some leaves so lower buds get more light without plucking anything at this point. I've been struggling a little with the added heat from that old led and today my other small fan shut down while I was at work so the leds burnt some of my top buds. I got two new fans but I have to install them first thing tomorrow. Also leaf tips burning and some clawing up and cupping on the leaves. Heat stress/low humidity is obvious here and I think there might be nute burn also. I've read that people tend to lower their ec towards the end of flowering until total flush so I might dilute tomorrow also. Day 25 of flowering Reservoir diluted ~15% and Ec now 2.3 pH 6.4. I was able to fix the old fan and I added one new to circle the air in the tent. Also I added towel in a bucket to get more humidity to the tent and foliar fed with humic and fulvic acid. Im not sure if the tip burning is getting worse or not so this is all im doing for now. Day 26 of flowering Some of the lower leaves have been yellowing from the edges for a while now and its happening so slowly that its hard to say if its spreading or not and I dont know whats causing it. Might be K def. but what is causing it 'cos I should have enough K and pH is OK. Might be something else and it could be light burn or nute burn. What ever it is its spreading so slowly that I have time to response. Lifted the lights again ~2cm and some of the lights are at their max height atm unless I do bigger change to the tent.. Still happy with the progress so far! Ec 2.4 Ph 6.5 Day 28 of flowering Nute burn has been going on for a while and now I think they really are nute locked, 'cos what I can tell I can see some deficiencies and toxicities at the same time while the leaf tips have been burning. Removed ~35% of water from reservoir and topped with less nutes and fresh water. Diluted to much less nitrogen and little bit less phosphorus and potassium. Ec 2.0 pH 6.4 and I hope they will come back with just this 'cos the girls have been growing so good to this point.
