Any ideas what could be wrong?

Probably a dumb question, but have you checked for pests? The leaves which dont appear to be infected yet, some of them look like they may have white specks.

 

What soil is it n have ya started feeding nutes yet?

 

Checking back side of leaves.

 

Yea if you look closely

 

It looks like a deficiency. Could be miracle grow or unbalance ph. I suggested bugs because you were in new soil 1.5 weeks this started happening and didn't get better. Plants wont be hungry in new fertile medium. Also I see the plants in the background which look fine and dandy meaning you have a understanding of what your doing. Could be the bucket doesn't drain properly. Idk

Starting from the beginning always check soil ph either with a soil pen, slurry test or run off reading. The issue starting from the bottom up indicates a medium or root related issue. Once a correct ph has been established check medium ppms with run off just to insure that there is food in medium. If both of those check right I'd wonder if this is the same strain as others or if you started in different soil not MG. Some growers have major issues with MG some do fine in it.

 

It's nute lock out, looks like potassium deficiency. It's from the crappy dirt and granular pH down. You could try transplanting into new dirt like fox farm ocean forest or light warrior or other good organic soil. If you have a compost pile that's good free dirt.

If u do transplant it, hose the root ball off with a garden hose to remove as much dirt as possible before putting it into new dirt. And don't use any pH adjusting chemicals from now on just water it straight from a garden hose or from your tap and they'll be fine.

 

Nah looks like calcium and another deficiency starting. I've had grows where I was so busy the plants drooping was my sign to water. Not recommended by any means js

As mentioned it could be nutrient lock out that MG is messed up. I figured that's what the others were in. If the medium wasnt bothering them I wouldn't expect it to bother that one. Normally you dont show numerous deficiencies at once unless theres a bigger issue. Unless its calmag and the grower hasn't been supplementing calmag

 

Same strain? Where you able to check soil ph starting there tells alot. Medium issues start bottom to top environment issues top to bottom. Knowing what is or isn't going on in the medium helps eliminate or diagnose

 

If you splashed ph down or nutrients on leaves they will burn. Did you really spill that much? Where it was on both those leaves? The screen shots I took are of what appear to be calmag deficiency. The chart is soil ph and what nutrients are available at that ph. Liquid nutrients are readily available you could use calmag ph to correct ph and feed. Depending on how off ph is giving good waterings of correct ph will eventually correct itself. If it's not like 7.6 or 7.7 if it's that high I'd just water at 6.2 many times monitoring ph until it comes back down then back up to 6.7 ph for feed and water.

 

That's your prob right there. MIRACLE GROW WILL END UP KILLING YOUR BABIES SLOWLY W ZERO MIRACLES AT ALL. I do NOT care what anyone says if u get a bad bag of that schwag than ya grow will go down the shitter. That brand is NOTORIOUSLY BAD WHEN IT COMES TO MITES, MOLD, ETC. I'd seriously look into making your own super soil on ya next grow. I have used FOX FARM OCEAN forest blend, it has SOOOOO MANY nutes that are great for indoor growing it's stupid. Def get off the main stream miracle death fast !!! But gotta say that's my own very educated opinion. I GUARANTEE A THAG WHEN U SWITCH U WILL SEE A HUUUUUGE DIFF.

Change medium fast. Do what u can to transplant the best way possible. U can beat that.

7.6 or 7.7 is pretty high for oh level.
