Toxicity/bleaching?--slow stunted flowering

[Muskellunge218]

howdy. My diesel is slowed in its growing and flowering. Budsite leaves are curled down and unstraight. From research it looks like toxicity. Soil Ph is at 6.7ish. I am following 's Hefty auto guide and am on the 3rd week of feeding. In addition to the curling of inner leaves, the main cola has practically ceased growth all together and is potentially experiencing some bleaching.(10" under 600watt LED"There is a white abnormality on the baby bud, although my eyes could be deceiving me. Check the pics and let me know your opinion, thanks y'all.

Try reducing your PH to around 6.0 instead of 6.7. Without knowing your nute build up in your coco, I would flush only until leaves are upright again. Try next water with PH 5.2. That should make your coco PH around 6.0.

PH 6.7 should not cause these problems you have but I assume you previously fed your plants a little heavy. Mind you, most nutes will reduce PH....so more info from you would be helful.

Musk, how much are you feeding, and how much water are you giving? I can't tell much with the LED lights on.
What is your soil mix?

Musky, you have a 600w LED, at only 10" above the plant? That may very well be part of, if not entirely, the problem,... Also, as mentioned above, we need normal light pics, feed regime info,.. same soil, OF? Soil pH is only slightly high, not in a problem causing range,....

Thanks for the quick replies everyone. My soil medium is Happy Frog. I have attached the nute schedule I have been using. As I said I am on the 3rd week in the schedule and have adjusted all 1/2 tsp to 1/4 , and over all have been halving or quartering the nute measurements. Feedings occur mon and thurs, with waterings occurring 4x week aside form feeding. For what it's worth, my Blueberry is on the same diet, identical, and is flourishing. I did notice some minor curling as well so both plants received a watering this morning adjusted to 5.3-5.4.

you using soil or coco? if soil I thought 6.7 ph is near spot on if coco then between 5.4 and 6.2 . ive had plants that look like that but my issue was cold weather. they do look dark so maybe cut back a bit on nitrogen but dont take my advice as I'm no expert, just giving you a few things to look at.

Uh oh. It should be soil not coco. Did I just make the soil even hotter with the watering I did this morning?

dont rewater or youll overwater, next water run through with ph 6.8 water , run it through slow and steady check ph of run off until you get 6.8 ish,
make sure the pots light before watering.

oh and stick your finger in there a good inch if it moist to wet leave alone until next day. better to underwater than overwater.
meters are ok but nothing works better than your pinky
and your lights should be atleast 18 inches above the canopy depending on your lenses 60 degree tends to fire more down so they need to be higher 90/120 lenses 18inches ish if in doubt raise them a bit.

hope that helps bud hehe, no pun intended!

Potential threat of ph flux at all?

 

[din5]

possibly.
but you have to look at it like this. it needs to be between 6.8-7 ishhh personally when I grow in soil ill use it, at 7.2 from my water and only adjust if I notice any issue coming. but most growers wont they will ph there water from day one. some plants can cope better with ph fluctuation than others. but you have already done the low ph-ed water, also some will say flush it with ph-ed water strait away but your soil will buffer it so it may well be ph 6-6.2 in the pot now depending what your run off was before.
so skipping up to 6.7-6.8 when it neeeeds water again wont be such a huge jump. you may get signs you may not if you notice any drastic changes over the next 2-3 days then flush with ph-ed water no nutes. also ph in the run off is not always that accurate.
just keep a eye on her, and adjust next time, you should get away with it hopefully. I'm sure other people will give you advice , best thing to do is wait a day and see what others say. and take the best from all the posts

but personally I would wait until next water to readjust the ph.

and make sure you raise those lights. I got my 250w led 18inches above the canopy. they will stop growing when they get to the point that they feel like they dont need to go up as the lights to strong. that's why they slowed growing.

make sure you post a picture of them here when there fat and ready for the chop be nice to see, as they look good now..
