Need your help dont know what to do

Seems like you are feeding them with a shitload of products...what is the NPK and ppm?

bio biz grow np kis4-3-6 and bio bloom is2.0-7-4

what shall i do to make it get the most out of it from this stage i am now

Something is clearly off so you need to figure it out. Do any of your products have cal/mag in them? Your ppm on nutes?

bio bizz is organic

in friday is going to 6th week

this is how it is now

Well then...

does it look good? do i have to worry about its condition?

and i forgot to tell you i dont ise cal mag or dont know if they do have inside

i have also some new photos

you need good ventilation and max 28C temp. these looks like nute deficiency

what nutes i need then? first thing after eading and came to my mind is nitrogen defficiency or mag? its details and i get confused i cant exactly what it is thats why i ask for your help since im a starter specially in autos and indoor

they told me from the shop to buy Revive from AN

and today its worse it has gone almost everywhere green veins and getting bit by bit the in between yellow . and also in new upper leaves

Get some epsom salts, give it a good feed (almost like a flush) with epsom salts, until you get lots of run off, then let it drain properly, then the next day pour on half a liter of 2ml grow per 1 liter. Then from then on, I'd feed 1ml grow, 2ml bloom, 1ml bud candy for 2 weeks, then 3ml bloom 2ml bud candy for the last 2 or 3 feeds. Bio Bizz bloom sends the ph up, where as their grow sends it down. That's why I think a lot of grows using those nutes look healthy until bloom in bigger amounts starts getting added. 1-2ml of grow with tap water is ph perfect, 1-2ml bloom with tap water ain't ph perfect!

You can wing it on grow, but bloom messes with the ph in the wrong direction. Top max makes it taste funny if you use it in the last few weeks.

Get some bio bizz fish mix, like the grow it drops the ph, but you can use it for the whole cycle. A 1 bottle line up. But you don't throw the ph out with fish mix for the whole cycle, so calcium, magnesium and nitrogen don't get locked out because of that.

I rate bud candy, i think it's good stuff. A few people bitch about the price, but it does make weed taste better and flower better, so £20 a liter is a bargain.

i go some new pohto s, also i went to the shop and showed them they gave some micro organism called bacto bloom
i bought also revive from AN shall i give those instead of epson salt didnt know about that and already went to the shop, need yur advice FEVS
