1st Grow

Am new to this. Growing 5 Fastbuds LSD-25 automatics. Living in a very hot house so using a portable air con to try and keep temps down. Made the rookie mistake of too much nutrients but quickly corrected that. Leaves showed a potassium deficiency so raised nutrient levels to 5 ml Part A and Part B Canna per 3 litres new growth seems ok. After flushing all pots with 15 litres of water ph'd at 5.8 I finished the flush with 3 litres per pot of nutrients with rhizotonic 6ml and cannazyn 7ml. At the end of week 3 side branching is appearing so have started bending LST. 3 are not yet ready to bend with LST and one is showing signs of overwatering. Am now in spring outside and temperatures are rising. Will be interesting to see if the portable air con can keep the temps down in the room. Growing in an open closet. Using Coco Noir soil which I washed thoroughly, Was the brick type because I could not get the bagged Coco. 75% coco 25% vermiculite in 12 litre fabric pots. Currently the coco soil is not drying out very quickly so after the big flush I am waiting to see how long that will take. Will probably give a small 500ml per plant feed every 3 days because I am not sure and don't want another deficiency. The lights I am using for veg are photography green screen CFL White lights. There are 4 per light fitting each globe rated at 225 watts but from the wall 75 watts, I have 4 fitting so am running 16 globes. I have a cheap chinese full spectrum to add when they go to flower! My air con broke down so another new one is on the way. This is not a cheap first grow for me but must finish it. Also growing 3 Crystal Meth Autos which I am starting a separate diary for. They, unlike the LSD25 don't seem to have experienced the same problems and are really nice looking plants. The blurb from Fastbuds was that LSD25 strain can withstand ph swings and is a forgiving strain, so far that doesn't seem to be the case. Also I used the Canna Grow schedule that tells you how much nutes to use at each stage but it appears they are wrong their schedule is far too strong if you follow the doses they recommend.
