First grow back

Hello everyone, reporting to you as of day 24 / 25 as of my count and seeing as 2 of the girls are doing so well, were on a somewhat scattered watering cycle as the 2 larger ones are demanding way more Litres than the others. Massive growth on the @Dutchpasion Auto Critical Orange punch and Auto Glueberry OG, 2 of the larger plants. The 2 smaller plants have put on growth since the last photos that I posted, I am noticing changes so we haven't completely stunted them, but possibly some mistakes / things I didnt do (like Cal Mag) that might have helped.The Sour diesel from @Dinafem is the smallest of the bunch but dont you worry little Runt, Sour diesel is one of my favourite strains so if you only grow a little I'll still be happy too smoke you. Also possible chance that my roots were somewhat cold so adding a greenhouse heater this weak has really improved my temps holding steady and I've noticed much more growth since this. Any advice is welcomed. Raising water temp when feeding seems too have done alot too, not shocking the roots everytime I water them. Much more efficient now. Really enjoying this again, 50 odd days and counting, less than 2 months now!
