Mine gets yellow/orange once in a while - I attribute it to the amount of iron in my water... nothing to worry about!

Sejnik
Mám stan 1m² a v něm 9x11L květináče. Po zalití s 10-20% odtokem vody mám problém s vlhkostí vzduchu až 75%RH.Vlhkost mimo stan je 55%. Udělal jsem pro snížení vlhkosti vše (včetně přečtení všech grow questions na toto téma).Otázka je: jak ovlivní menší zálivka výslednou kvalitu?

3 part ph perfect nutrients and ratios
Can anybody advise on the nutrients I’m using, I realise I should be lowering nitrogen levels so can I put say 2ml micro 1ml grow and 4ml bloom per litre now? Thought I had nute burn but I let the roots dry out a bit much so the tips higher up have burnt a little.

High ppm in drainage
I flushed coco two times with 8-10 litres with CalMag (200 ppm) and it does not help. You can see in my comments to the last weeks of the diary that it doesn't matter how much ppm I water the plant, it is always 2-3 times more ppm in drainage.What should I do?

Is rain water a good source of water?
Would rain water be a good source of water for indoor plants? I have always ph’d tap water; however, I have two rain tanks that I use for my outdoor tomato garden and was curious if rain water works well with cannabis. My tomatoes love it.

Why the smallest plant does not drink nutes ? The one in the video that I mention is having 500 ppm run off . What shall I do with the nutrition in order for the growth to explode like the other plants? What else I can add in this case and do I need more light for this amount?

Ph and ec in batmix??
Most of the people here telling me that i should regulate ph and ec when growing in soil (batmix) But on plagron website: Should I adjust the pH and EC values if I grow with Batmix? No, combined with our 100% NATURAL Grow Style you don't have to regulate the pH and EC value

Co2/Temps/Nutrients
I pushed the temps up and got the VDP on point w/co2. Now since the plant is drawing a lot more water up through the roots, I've noticed very slight nute burn on the newest leaf growths. Do you have to drop PPM's as temps rise? I thought it was the other way around?

Feeding right after repotting (coco coir).
After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.
