Lemon Haze x 3

Just received 3x Lemon Haze clones from a friend who is moving abroad. They haven’t had any light, food or water for a couple of days. Set the tent up with a fan and 600w light but have very little time to get it perfect and find my thermometer/humidity stuff. Hopefully will be in the perfect environment in the next couple of days. I’ve been told they are around 4 weeks in veg, photoperiod, but think they may be slightly older. One has been topped already. Please feel free to drop any suggestions, comments etc. This is my first photoperiod grow, second in total, so any and all help appreciated. Going to mix up 5g of Ecothrives Biosys Instant Microbe Tea into a litre of water I’ve had, trying to dechlorinate, as a good start. May add some Cal Mag too because of some leaf issues. Aiming to water every three days, in current environment/pots. Keeping one for a friend until it’s in a better condition. Mid-Week Updates** Sprayed the plants with a Techboost EX:EL Foliar Spray and applied some LST to the pre-topped plant, on one of the main stems.
