Check your temps, leave the fans on longer than an hour maybe? I at least have a small fan running 24/7 to keep the air moving somewhat.

Try an osculating one.

600watt is serious sh!t for a few small clones, would do for a few 1 meter plants let alone these. Peace

Wow, new growth is good, looks like you got everything in the balance, old damage is like non existent now.

What ferts have you got, there still in nice big pots for their size and some seem a lot bigger than others, sweet set up too, maybe move the ballast outside of the grow room if thats what that is in one of the pics, probably be cooler outside for it and generate less heat in the grow room depending on min max lights on temps. Peace

nitrogen deficiency; starts yellowing at lower branches, climbs up the plant. give it nutes @half strength. plants grow faster at half strength(900ppm-1500ppm). plants grow slowest at 1/4 strength(300ppm) and full strength(2500ppm). also K should be the highest nute always, it regulates water...

they are looking better, but im still noticing purple stems. they are lacking nitrogen, feed them a nice all around 20/20/20 fert to get them on the right track.

I just got the fish mix, believe its an awsome product from biobizz. One thing i warn is biobizz seems to contain no calcium, maybe a seperate calcium rich foliar feed and some epsom salts might not hurt.

i have biobizz grow, bloom and top max, should i get some epsom salts too ? what sort of calcium feed would i also need ? the ballast is moved and you were right its one hot little lady :) left a mark in my room lol its outside on a tile now beside it. the purple branches are only on the 2 largest ladies and not all branches i think its because they are growing nuts compared to the other 4 i think they are a different strain but all leaves are nice and green on those 2. many thanks for the input man.

Peace

I can only advise what i know, well documented biobizz is deficient of calcium but lime and water may contain enough for you already, i would just get these products for cal and mag and not take chances. Its up to you in the end, they look ok for now, if purple spreads on stems post sum pics and lets see but just go easy on the grow in those big pots. Peace
