I have a Pineapple express in week 4 of flower. I thought at first it had a mag deficiency but after flushing, adding Epsom salt and cal mag+ there is no change, its actually worse. I think it might be Nitrogen? I dont know any help would be appreciated. Is it too yellow at this point in flower to do anything?
using promix hp
feeding
gh flora series
calmag+

Ph'ed to 6.0

ppm ~1200-1400

Ok that makes sense. I was told to treat soilless mix like promix hp like hydro when feeding. Do you think they are saveable?

As far as supplements in addition to the flora series (grow, micro, bloom) I'm also using GH Kool bloom, silica, some molasses for sugars some Epsom salt

They are way way under fed. Its to late now to bring them back to full health. Thats really yellow. Hit them hard for the last month they are alive and hope for the best, they are begging foe nutrients.

Personal that's what I thought. But I'm n feeding them a lot as it is so I didn't want to give them more without some advice. Would you say it's nitrogen or mag? Also, with it being so far into flower how much should I up the nutes?

I don't know if I'd feed them at a greater concentration. I do not believe that will help. To me with your additives it seem to be a little high in the K so maybe a good flush and start with a balanced diet.

Next time try a more balanced nute mix. For grow I try to keep a ratio of 2-1-2 and flower 1-2-2 ratio with around 5 % cal and 2 % mag. My flowering mix ends up being 5-8.5-8 and my plants seem happy with ppm being 700-850.

I've got four different strains in a 3 X 3 tent -all growing under an Area51 SGS-160 and three 4-bulb LEDs (Home depot) in each fixture around three sides.

One of my plants looks just as yellow as yours, while the other three, under the same exact conditions and in the same soil, same fertilizer, etc., are doing great.

Apparently, some plants must feed way, way, WAY more than others.

I haven't tested the pH of my H20 but I now suspect that the water filter I installed is changing the pH to acidic. I'll get back to you on that once I find my pH test kit! I know it's somewhere around here…...
