Week 4 flower, intense yellowing.

SoMEgrowNewb33 · Apr 22, 2015

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

I fixed the post ^^ any help would be great!... First grow ever so go easy on me

see how you are not letting P, Ca and Mg be available according to this chart. Also when this happens its a domino effect of lockouts ( N,P K etc) Boost your PH to 6.5-7.0 add full strength nutes and feed.

Still not enough info. I believe GH recommends 600-700 ppm. What supplements are you using?

SoMEgrowNewb33 · Apr 22, 2015

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

SoMEgrowNewb33 · Apr 22, 2015

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.

SoMEgrowNewb33 · Apr 22, 2015

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?

boilingoil · Apr 23, 2015

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.

Is that the dry koolbloom or liquid ?

SoMEgrowNewb33 · Apr 23, 2015

Liquid

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…...

Seems like Diabolical hit it on the nose, looks like a ph problem.
Are you feeding at full strength???
