my plant is 3wks in flowering, & the leaves are turning yellow starting on the left side of the plant & getting less yellow as u go to the right side, its also the same with the leaves themselves that are yellowing, its starts on the left side of the leaves & lessens toward the right side of leaves. the runoff ph is exactly 6.97, useing advanced nutrients "Big Bud", & Growtech "montster bloom", with Bontanicare "blast off" & molassas (not all at the same time). room temp is 78-80%, humidity is 55%, & plant is in a 3gal pot in a organic mix soil.
this 1st pic is the worst, this has been progressing for a wk now, most leave have already fell off, but notice how the problem starts on left, its hard to get pics of other damage b/c its inside the canopy, but you can grasp it from the other pics.
your in lockout, you have several defeciencies yet they have been over fertilized "the Claw" is present the leaves not yet affected are very dark green , from nitrogen toxicity. the claw will remain even after the plant recovers so dont be concerned complete a soil runoff PH test....... with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...test the PH of this water.... you need to flush your plant regardless of the PH runoff to leech off the excess ferts Flush with PH corrected water, till in optimum PH range, 3 times the volume of the pots rule of thumb but may require more EG: 1 gal pot = 3 gal. flush back off of your fertilizer for a couple weeks and dilute the strength your using
is it ok to still use the molassas & blast off. one last concern, my flower ferts have no nitrogen in them, so i dont understand how its nitrogen tox
ok got another prob, i did everything that gg said, it worked for the day, but today almost all my fan leaves have fell off. will it survive till harvest w/o out most its fan leaves, & even the leaves around the buds are turning yellow. my runoff ph is 6.88. heres the rest of the orginal prob http://forum.grasscity.com/sick-plants-problems/165613-i-cant-correct-my-ph.html
Looks like too much nutes and maybe too much water. It's normal for your plant to go into shock if you make big changes to the soil. It will need at least a few days to adjust itself to it's 'new' environment. If you flushed it 'properly' you have effectively overwatered your plant and it will take quite some time for that to correct itself. Right now, sit down & relax. I know it's hard. I've been there more then once.....
Aha, I see how that would fix the overwatering quickly : 2H[SUB]2[/SUB]O[SUB]2[/SUB] -> 2H[SUB]2[/SUB]O + O[SUB]2[/SUB] + e- So you'd get some extra oxygen but the excess water is still there. Did you use a 3% or 30% solution? O hell, in any case wait and see like you said.
