Grow QuestionsCant stop N deficiency

Cant stop N deficiency

PersasHstarted grow question 4 years ago

Im not being able to stop the yellowing of lower leaves going up. Lowere leaves are diying and the next level is yellowing. A couple of days ago i fed it with N ti stop it but does not seem to work. PH in runoff read 5.9 with 6.5 input water ph. Any ideas on how to stop it?

Since you're in flower and it's pulling mobile nutes up from the lower leaves, I'd guess you need more bloom nutes. P + K + Mg much more than Nitrogen. A 5.9 pH runoff could be locking out some of the nutes too, I'm thinking Mg specifically (which prefers at least 6.0 or 6.5+). I suggest you try feeding it with a higher pH water to get the runoff into the correct range, and see if that helps.

Hi, it’s an auto! Defoliate and feed some good old water for now. Autos seem to like less food.

Need to list full nuet schedule and what you have done to this point as if they are not taking up N then something may be wrong at roots

Leaves at bottom of plant starting to dry out and or get brown edges and twist. It is a coco grow so different than soil. I just moved tents but had issue starting beforehand. Is this a deficiency or something else. Please see recent pictures and see old and new set up. Thanks

Would Epsom salt be helpful for these brown spots? If so, how many ppm? Is it OK to reduce pH with citric acid and distilled water in nute mix?

Early flower leaf oddity Noticed odd markings on leaves, some top or mid canopy some below. They vary also - from heat stress, shiny spots, residue from Insecticidal soap or wind burn in odd spots. I’m about 2 weeks in flowering. Temp was 27 degrees, had to defoliate massive fan leaves... see b4/after

Do you think my plants are having trouble due to the mulch layer being disturbed? Or is it possible I am actually lacking in nutrients? I feel my soil should have all my plant needs. redid the mulch layer this week.Im still seeing a few gnats, are the larvae feeding on root hair?

What should I do about the old leaves? likely ph imbalance and/or nute deficiency (Phosphorus -redding older stems + browning of dry leaves) and Nitrogen- slow light green new growth) - the issues seem to be resolved, but the leaves are flaking almost. mostly referring to plant 2

Hey guys had a quick question for you. I’m giving my plants about 500mls of water every 2-3 days and water when dry. I am currently growing in promix and I’m already seeing a few roots near the base of the plant. Is 500mls of water enough for a 1 gallon pot?

Hi, I'm seeing some burn/orange spot, but mainly on older leaves. It looks like an overfeeding ( potassium or so ). Could you let me know your impressions ? I am using already a lower AN dosage than recommended, I think I will reduce even more ( maybe use half their dose only)
