Indoor you must simulate outdoor conditions.
The good thing with Indoor farming is that you can simulate the best outdoor conditions because you got the control on it .
That means , when it rains outdoor, in 90% of the case , itβs cloudy with no sun shining !
Simulating the rain by spraying your seedlings under a 400w LED which is supposed to be the sun , will lead to burned white marks on the leaves .... . By the way , you donβt need to keep a high humidity level , they are seedlings with a root system and they can take the water from their media , not like clones with no roots system .... another thing, rain water is not tap water or spring water or mineral water.... rain water is at pH 7.0-7.1 and EC 0 to 10 ...
Purpling stems ... purplish is the first sign of a Mag deficiency, it comes from many different factors, but indoor itβs mostly from overwatering or too much light.... Purple strains gets purple flowers , but only the flowers are purple π In your case Iβm suspecting both problems, youβre growing Ganja my friend, ainβt no water lilies in a swamp π plus blasting young seedlings under a 400w led at 35cm wonβt solve the problem neither π
When it rains and the water starts to drain into to soil the roots hairs retracts and the main root starts to suck the water .... here is where you understand that the main root is used to intake water and the root hairs are used to intake minerals....
So, technically from what I can read, youβre simulating a swamp somewhere in Asia during the monsoons under an Australian sun during the summer .... now you can understand something is wrong, no ? π
And this is where you must understand that the 3 most common problems indoor are:
Too much light
Too much water
Too many nutrients
Stay away from these 3 problems will give you the best Ganja π
