Feminized Indica and Sativa mix!!!

Day 24: 600 W LED Light schedule 24/6, ventilation is the same +15 min after the lamp switches off. Water: 50ml per plant so 2x 25 ml per day per plant. Fertilization with bat guano and the same amount of water on Tuesday, Thursday, Saturday. They grow nicely! Someone commented that it looks more magnesium deficiency problem instead of burning so suggested me to add Epsom salt to the water. I ordered Epsom salt so I will give it a go! Thank you! I still believe that I put too close the lamp so it was related to it also but I can see spots on the lower leaves so there is magnesium problem here as well. By the way, they look now beautiful! Blue Sherbet S1 is slower a bit but it is Sativa. Day 25: They started growing rapidly. Day by day they are getting bushy and growing nicely. Day 26: Epsom salt has arrived. I will start feeding them with it. I will mix one tablespoon with 50 ml water 2x a day and I will do it on Monday, Wednesday, Friday. Day 27: As I mentioned in my other diary the last 3 days was crazy hot especially today in London 38 degrees. In my tent, there are 32-32.5 degrees. Luckily, I have direct ventilation on the plants so they won't feel that much heat, but it is crazy... anyways They are getting really bushy and keep growing. I can see some yellow pots but started feeding properly them with Epsom salt and bat guano. Day 29: I retrained (LST) they so tried to spread the sides and bend more the main stamp and also changed their position so I placed them to a different corner. Day 30: It looks like that the Epson salt is good they look better green also now I just damage some leaves as I retrained them. Tomorrow starts the 5th week where I will do some Topping to them except to the Blue Sherbet S1 because it is quite small for that. I will use only LST and FIMing for her.
