Raspberry Cough problem

Hi all i posted a few weeks ago about some mild nutrient burn. Now the ladies are starting their 5th week of flowering and three of the four plants are starting to show some yellowing. The pic posted is of the most yellow of them. I have been feeding every other watering at around 600ppm with the GH GO series which includes cal mag and bloom nutrients, I also add 10ml of molasses. Any help with the problem seen in the picture? some of the newer growth has burnt tips as if I have overfed, but the lower leaves are completely yellow. Thanks

maybe half the nutes or just flush with phed water n let her use up whats left see if it clears as i always say im new so dont take my word for it or possible zinc defficiancy if my diagram serves me correct lol maybe someone who knows there shit can clarify just like a stab in the dark

Most likely needs a flush. Think about how plants grow in nature. They aren't constantly fed liquid nutrients and they grow just fine

10ml molasses per how much L water?

Your plants are N deficient, you could add a LITTLE boost but do not overdo it as excess N can stunt flowering.

It's not Zinc, It's NOT N def!

CLASSIC P tox! Too much P too early!

DO NOT change over to "bloom" foods till at least 2 weeks after the time flip! Use the veg nute for that 2 weeks. Then MIX veg and bloom 50/50 for a week and THEN go 100% bloom nute!

That stupid chart should be scrapped! Causes more problems then it solves.

Nutrient makers (the vast majority of them) feed charts have you change too early and have too much P available....While you go into a grow shop for Marijuana specific nutrients - there is NO such thing! Nutrients are nutrients - period! It's how the NPK ratio is and at what times you change that ratio that make it any kind of "plant specific feeding". Never plant specific nutrients! The charting they give is more flowering houseplant oriented ! OR the makers attempt to compete with each other on how far they can "push" a plant to produce and "claim" that they have the best..... Sadly they do that geared to all of you inexperienced growers looking to get the biggest, best and fastest......The sad reality of that scam is lower quality!

You could try adding some N to mask it by slowing the yellowing progression down a bit....I would just run them out and follow my guideline next time!

Good luck
