It’s gotten a bit worse over night. Today’s first feeding I’ve upped the BioBloom to 10ml/gal and Calmag to 6ml/gal at 6.85ph, 1.07ec and 740ppm. Runoff was 5.98ph, 1.01ec and 690ppm.

I have a Zkittlez auto in tupur mix. It’s 9 weeks from sprout and starting to flower. Tent is always 55-65% RH and 70-75°F. Feeding it 2-3 times a day 6-7/gal GO BioThrive Bloom (2-4-4) and 5ml/gal CalMag (2-0-0) in RO water, Ph to 5.8-6.0 and EC 0.8-0.9, 550-650ppm. Measured the runoff at ph...

I’d say I’m likely closer to underwatering. I let soil dry out quite a bit between waterings. I’ll lower ph and see if it helps.

I don’t think it’s natural, not this early into flowering.

Hmm really? Doesn’t look like the usual signs of cal or mag def

Yes plenty.

I have an auto in early flowering that’s starting to yellow mostly on the fan leaves in the middle of plant. It’s a strawberry cheesecake from seedsman. It’s in Fox Farm Strawberry Fields soil. It’s 6 weeks from sprout. Lights are a 100w output blurple led and a SunSystem HPS 150. It’s been...

I have a 100w output blurple and put a SunSystem HPS 150 in there about 2 weeks ago which does output some heat but with the exhaust fan in there temps didn’t rise much at all. Maybe 3-4 degrees. Temps are always around 75F and RH usually 55-60%.

Also an off topic question.. Does this look like the start of a phosphorus def? I noticed it 4 days ago and since given it a half/half mix of BioGrow(4-3-3) and BioBloom(2-4-4) at and EC of 0.7 and 450-550ppm. And today I’ve just given the bloom nutrients at the same strength. Calmag is added...

Wouldn’t that be a horrible idea in a coco grow? No soil to buffer.

Ok so like Ren said, mix my nutrients with the water and only pH after I’ve taken it from the res into my gallon jugs? Thanks for the info guys, always it’s good to know why it’s happening and not just what is happening.

What about the air pump would cause this?

It’s general hydroponics ph down

Ok I wondered if it was my tap water or the nutrient line I use not being made for hydroponics. I’ll try switching to RO and see if that helps. And so it would not be harmful to keep using more pH down in the meantime?

I’m not growing in a hydro setup but didn’t know where else to ask this question. I have two plants currently in coco that I’m handwatering 3x daily. So instead of mixing, ph’ing and measuring my nutrients in a gallon jug 3 times every day I’m trying to make a “res”. I’m using a plastic tub...

No, they flower based on their genetic time frame. Just gotta get them off to a good start and train them to grow as fast as possible.

Ok yea I’ll have to get on that. Thanks for helping!

Sorry, duh. The tent is 62” tall, 58” long, 22” deep. So 8.86 sq ft. I’d say the canopy will be in a 2’x3.5’ space if I had to guess. @tslonige do you get dense buds with your LED’s?

Ok. Would you recommend any other in that range? The 3 were really just what I’ve looked at so far.

Yea wasn’t bad at first but quickly becomes tedious. So until I get a drip system I could technically get a bin, mix a few gallons of nutrients, aerate it with the fountain pump and scoop out what I need and water right? Just pH it once a day?
