A 5 inch cloth pot and watering only every 3-4 days sounds like it could be limiting the plants growth.

I've done some work in big commercial grow rooms and I've never seen dry salts being used they're buying 55 gallon drums of liquid nutrients never understood it or bothered to ask them

oops messed up my decimal there, should be 0.99g, their feed schedule lists 98.94g per 100 gallons

According to Jack's feed schedule it's 2.4 EC 3.8 5-12-26 2.5 Ca Nitrate 1 Epsom

I thought the full spectrum Apogee is made for lights like LED and CMH? What limitation are you anticipating with the Apogee?

Your tent is starting to sound a bit wild, 9 fans and 6 hygrometers? bongsmilie o_O

How big is your tent and is your exhaust fan big enough because if your room is dry it should be bringing the RH in the tent down if it's exchanging enough air. A few weeks back I picked up a 20 pint Arctic King at walmart for $75 it was marked down.

You did a fake hydro grow before? :eyesmoke:

I didn't start the thread I just wanted to talk about some Bruce Bugbee shit

Looks good are you gonna flip them soon? My first grow came out nice I think it was beginners luck. Had my share of not so nice after that from time to time.

Something to do with the leaves absorbing infrared light I believe. Also gotta take into account different strains tolerances and thermometer accuracy. I've let my grow area get up to 30C in veg and the plants didn't seem to care. I've read a research paper where they grew tomatoes at 40C with...

Guess I glossed over that they were autos, never messed with those. I agree probably not worth the time to get a little nug.

Leaf temperature should be lower than ambient due to transpiration. Your plants look happy I wouldn't dim just when they're gonna start putting on weight unless you see taco leaves, end of day droop or bleaching.

I wouldn't put all your faith into the lux measurements since they are made to measure how humans perceive light and not the PAR that the plants care about. If you're gonna run on the bleeding edge of co2 and DLI it probably warrants investing in a quantum meter. Ultimately though you're gonna...

Citrus Rush, hope to find something tasty.

What ratio A&B? Looks like maybe too much K, maybe need more part A and some epsom salts if the yellow in-between the veins persists. 1.2 EC might be too high too for now especially if you're feeding multiple times a day.

Something like Jack's 5-12-26 already has micronutrients in it. Kelp and other organic based products can leave shit in your reservoir it's doable but just needs more maintenance.

I feed coco at least 400 ppm from day of sowing the seeds. I'd do 3ml / gal calmag and follow GH's feed chart for week 2: micro 4ml, gro 5ml, bloom 1ml and then dilute to 450ppm.

Soil looks pretty dry how it's all cracked on top. 30% RH is too low as well.

They look like they started recovering I wouldn't be ripping them up. Get your humidity up, use smaller pots to start seeds next time and don't water them so much.
