Marketing my man they are 0-800w
Have to disagree... ph doesn't really mean much especially when watering a buffered soil. You won't be able to influence the ph of the soil but o ly temporarily. The soil contains buffers that will change the ph.Wow, I'm pretty shocked nobody gave you the right answer.
There's no need, or use for molasses until mid/late flower, but it is contributing to your problem.
6.2 is WAY too low for FF. Your PH has locked out most necessary micro, and macro nutrients. You want to feed around 6.8 in soil. It's early enough to save em, but you need to act quick.
There's enough nutrients in FF for about 3 weeks.
Take out a cup of soil from 1 of your containers, and run 7.0 water until you get enough run off to test the ph. Post your results.
Start feeding plain water at 7.0, and within a week they'll begin getting healthy again.
Keeping the lights too close is NOT, and very rarely a problem in veg, unless your lights are burning the plants.
The only real good advice I've read was stop using molasses. Molasses with drop your PH. Also keep your water temps between 65-70 when feeding.
If you have any questions, feel free. I've been doing this a long time
The white spots are probably nothing, but if you got them from clone from a friend, or dispensary, who knows. It's worth grabbing a scope, and taking a look.
I agree with you on the lockout but I feel its a root zone issue because it's not just deficiencies but the leaves are drooping badly and transpiration is obviously not doing well..no transpiration no nutrients. From the pics I can only say I have seen this with over or under watered plants, bugs, foliar sprays or very high salinity like in the case of a water softener.I like your argument, however, it's not buffered enough, and it takes time for a ph of 6.2 to get in range.
So even if it were heavily buffered wuth lime, or oyster shells, it takes precious time he no longer has
FF isn't thr same FF as when I grew in soil either.. quality control stinks, the soil is much "hotter"....
Why risk it? Look at his plants, they are suffering from lockout.
I agree. I wish I knew a way to measure blurples accurately without a par meter but lux does work well.Those are way too powerful lights for clones imo, even when dialed down.
I've had some plants that went apeshit under my 480w Led but recovered well under a a 150w cfl.
