First try

Today I added one 100W light more so now I have total power of 300W Girls are growing strong and maybe next week is time for flower? Havent done anything to my nuitrients, only added more bacteria to reservoir. Day 3 Some of the leaves are getting yellow and tips are burning. I think that my lights were too close and it is light stress from that added 100W led so I spread them wider and lifted a little bit. Day 4 Ec was 1.7 so I diluted it with only water and additives (Golden nectar, Supervit, Silicon max) Ec is back to 1.5. Also I removed some lower leaves from two of the girls cos they were getting in my way all the time and I would like to see how they react to this. Adjusted the fans today also cos leaf tips are turning more yellow and burning so I want to remove some stress from them. Day 5 Added 8 liters of water with additives and MgSO4, 'cos friend said they might be suffering from magnesium deficiency. Also took some clones today and removed all the extra growth tips to promote the growth of all the tops. I probably wont touch 'em anymore until its time for flower. Day 6 Added weekly dose of bacteria couple days early and added 50 grams of dextrose just in case the bacteria needs more food. Leaf tips still burning a little bit but still the growth looks healthy. Some slowth in growth but might be from the stress from cutting. Also added some CaCl2 and MgSO4 to my evening foliar spray. Day 7 Last day of the week and preparing for flower. The pH of the reservoir have been steady 6.0 for whole week and I havent done anything to it except today. I dropped it from 6.0 to 5.6 in three sets. First in the morning 6.0 -> 5.8 mid day 5.9 -> 5.7 and finally in the evening 5.7 -> 5.6. The pH have been so stable for whole week so I wanted to give it a little shake to provide all the nutrients needed before flowering.
