1.4 EC? That high? That's almost 1000 ppm isn't it?

So could I just repot them in pro mix and use the jacks drain to waste? If so what pH should I mix the nutes at? 5.5 or 7? Thanks again for the info

I'd just say to flush the first but I'm not sure how effective flushing MG mix would be.

Yeah bro your hgk should finish before your nanners start pollination. I'd let them pollinate itself for some fem beans. I mean I always find myself wishing I had a few fem beans for outdoors come spring!!!

Looks like your mix is too hot for your first plant. Did you recently start feeding them? And did you FIM the second plant?

Looks like the beginning of a defficiency in Nitrogen based on the lighter green toward the center of the newer growth. The bleached/brownish spots look like a moisture or ph issue. I'd take care of the N def first and keep an eye out for any more spots.

Yeah those little buggers can wipe out your entire crop if left uncontrolled, besides being potentially devestating they are near impossible to get rid of once they get a foothold in your room. There are a plethora of miticides on the market and I have used most with mixed results but never full...

BTW will I need calmag using the GH for hard water? I realize the whole point of using the harwater formula is because of excessive calcium in the tap water but just want to be sure. Thx yall

Right on, thx panhead, my tap ppm is right around 250 ppm, so I should get GH for hard water

Gotcha, makes sense. Gotta get some hydro nutes, I didn't figure I'd be able to use the Jacks but I have sooooo much of it I figured I'd give it a shot. Thx brotha

Yes its first use hydroton, I rinsed it really well... hmm I never knew that about hydroton, thanks man. Should I just run water through it until the pH stabilizes or is there a better way?

What's your pH look like? Looks like a pH issue or over watering....

Just had an idea, I start the seedlings in jiffy pellets..... maybe the peat is the problem??? Just a thought lol

Hey all ive recently returned to the hydro game and am having a HUGE problem with my pH. My tap water has a starting pH of 7.8!! Yikes I know but no RO because my water leaves huge mineral deposits in my mushie humidifiers so I can only imagine how fast it would trash a RO system. But anyway...

Same boat here in Ohio, freezing winter and hot as balls summer. I went ahead and invested in a small a/c while they are cheaper ATM. Cheers and good luck brotha

This is a pic of what happens when your heat source fails and temps drop into the 30s

Yeah, definitely so, using hydroton or a similar, well draining medium

I'm wondering why everyone here is bugging so much about drowning their plants? If it were that easy to drown your plants then I would think DWC would be impossible. As long as the water is oxygenated, and in an ebb and flow system it almost 100% of the time is, you shouldn't have any worries...

Hey alpha, how often/long do you flood? I plan on flooding 15 mins each hr up until week 3 flower and then increase to two 15 min intervals per hr during lights on and 15 mins once per hr during lights out
