Help! Burn/deficiency

Just got some clones a couple weeks ago and they are not recovering like I had hoped - I read all the deficiency and I think I have magnesium deficiency or potassium - with a possible molybdenum - I will post some pictures so that hopefully someone with more experience can tell me what’s up - FYI this is my first serious attempt at growing.

What is hard to see on the pics is that almost every tip either has a light burn or purple/pink tips + purple and red serrated edges

Last pic is a bag seed I started 1 week after getting the clones -

450w LEDVipar - so far i have fed nothing just purified water, Clones were rootbound when i got them, looked worse than pictured. When i transplanted I used purified water + rooting agent. currently pH is not being monitored, getting a tester this WE. Medium is Fox Farm ocean forest - Clones were in coco prior to transplant, grower said they were getting 1100 ppm

humidity is a problem right now (81% as the high, 64% as the low) - and Temp is not as much of a problem but not ideal (70 high, 66 low)

I guess you have a few things to check and correct before much can be said with regards to deficiency or toxicity or ph lockout possibility. Be careful with that high humidity and low temps..at 66 degrees and 70% humidity, it's an invitation for wpm or another mold.

would a cheap space heater from kmart do the trick? or is that a fire hazard (dont really want to shell out for a infrared heater)

Anything that is made to provide heat will 'do the trick' of making it warmer. Not sure what you mean. As far as fire hazard goes...the units are sold as they are..they are not sold with the intent of causing a fire. A fire hazard when using a store bought unit like that, can only come from your surroundings. So ya..if you have the space heater and using it in a puddle of water, or with curtains and such draped all over it..yes it's a fire hazard..but as is, from the store and plugged in to the wall and used 'normally'..should not cause a fire..like anything else:) You buy a stove, it's a fire hazard if you leave oil burning on it unattended or say putting a stack of papers on it and turning it on..that would make it a fire hazard.

I just use a cheap space heater but have it plugged into a baseboard thermostat to make sure it doesn't overheat the room. If you've repotted them I'd snip off the really damaged leaves and see how the new growth comes in. Could be fine in another week or so.

:peace:

So they are most likely deficient since you say they havnt been nuted. Prob cal mag being he most prominent. You say you got root bound clones. Where they by chance neglected by the old owner and left in the dark? It looks like it was starting to flip to flower but was promptly put on a proper sched( prob when you took ownership) they have some weird bladed leaves growing, a large shoot coming from the main bush. Like it thinks its revegging. It doesnt look like it belongs in the E.R so thats good. Patience, time, and a little cal mag would be my advice. Cheers man.

That's quite the advice lol. Cal-mag, of course. Wondering what in the pics show a calcium deficiency?..and how do you know he's deficient when you have no idea what his ph is. Previous grower was feeding them at 1100 ppm, which is ridiculous considering their size! He's using ffof, which is filled with food to begin with. I wouldn't suggest dumping more ferts in, when you know for sure they have been overfed prior and when you don't know the ph as well. You switched growing mediums, i'd say first and foremost, make sure that ph isn't out of whack and take it from there. I dont see a calcium deficiency in those pics, why force cal-mag?

from pretty much everyone of these pictures.

Having a light tip burn or anything to do with red discoloration has zero to do with a calcium deficiency. in any case, best of luck!

Thank you all for your insight - I will be getting the pH meter tomorrow. I managed to get the Humidity down (49%-43%) - temps are still not ideal (68 ) - the stems which were previously all purple/pink are now turning green slowly but surely (i'm guessing this is a good sign)

'generally', slight purpling of the leaf or tips, 'can' be caused by cooler than normal temps. It can inhibit phosphorus from getting through adequately and that will leave behind a hint of purple. As long as your temp is very close to 70 and doesn't swing too much from lights on to off, it'll do..the humidity is more important to keep in check..above 70% in veg or above 60% in flower, can create unwanted issues!

Few details missing like what are you feeding and watering and is ph being monitored? Grow medium? Lights, temperature/humidity? Just from the pics, some look to be nitrogen and magnesium deficient. Maybe this pic can help you on your search...
Thanks for that pic! Large Print worthy.
