Organomananswered grow question 3 years ago

I would suggest going back and giving her a half strength dose of "grow" nutrients every second feed for a couple of weeks, this should restore some health, she is suffering with a nitrogen deficiency and this can not be cured with cal/mag. This yellowing problem/nitrogen deficiency is common amongst people who switch to straight bloom nutrients too early, cannabis still needs adequate nitrogen during the first few weeks of flower development. Hope this helps, Organoman.

Too much calmag on a regular basis can interact with your P and M uptake and cause dual deficiencies. Looks like yellowing started bottom up which typifies N def. How much are you watering per 24hrs? Plant that size would probably need .5-1L a day but I would try it 1.5L every 2-3 days.

Hello my friend. Looks like you got some PH issues causing lockout mixed with some nutrient burn. I would flush the ladies and cut the nutrients back a bit. How many ppms are you running them and what PH are you giving them? Also please elaborate on soil make up.

Deficiency?My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.
