Leaf damage? Dtw coco

I dramatically cut the Kongs krush to down size it and the other as well but was more babied. Theyre both growing 5 tip leafs again. I chopped back some more.

I think its a node thing that at some point the growth tips mature and grow more tips on leafs. Being cut down restarting. Maybe also location of branch.

Could be wrong just my guess, look fine otherwise. At the least it may be stressing it chopping in half almost.

They were fed 4x a day but now back to 2 I hope that dont bother them being so old and root bound.

New plants in question, Watermelon Ultra clones in like 3 weeks veg from potted. Is 10k lux enough to cause issues? Leafs look stressed. Cant find my ppfd calculator but its like 222ppfd? What else could be wrong?

.5ec tap with .3 maxibloom total .8ec ph6.0 all the time, fed twice a day. dtw coco/perlite. 75F 50rh. fecida cr1200 its a strong light almost on off setting.

My clones of same strain in another tent with 4000lux look way healthier. Guessing thats the issue but just making sure, flipping to flower soon. Dimmed the led in other tent to 5000lux.

It's not the light. If I took a guess, I'd say not enough nutes.

Half the ec of the tap and increase total ec to 1.2-1.4 with base nutrients
And get temps up a bit

I have recently lowered to .8ec total it would easily explain. Used to do 1.1ec but looked overfed last time or just right.

I would need to get a ro system to cut the tap idk if I can do that any time soon. It would be a pain to fill reservoir. If raising nutes/waterings doesnt help I ought to try that next though.

Did you ever find out what's making up that tap water?
Seems damn hard

I see lots of people with .5ec make it work its when its passed that, that people start to wonder. Hope I can work wth it, would make things easier.

I looked at the water report and told the majority of whats on there to members here and they said it was fine, just high in cal and mag. Nothing concerning.

Super alkaline 8.2ph. A cup of water can raise the ph as if it was ph up.

Yea this is the second time running this strain last time was 1.1ec 3 gallon pot 4x a day fed and was fine until my ph meter gave out and fed it pretty much soda with ph of 4. Even then it looked ok.

Burned it with the light a bit too. I switched to ph drops to make sure I stay accurate. I just burned that solo cup plant so down sizing from 3 to 1 gallon I tried avoiding that but perhaps too soon.

They were dark like well fed is a good word, almost too much, n toxic. Idk its why im here I still have a lot to learn thanks for yalls help.

If you add nutes and ph drops to 4-5.0 can you add ph up even though it will drift up back to alkaline ph from the alkaline tap water? Is it ok to then add ph down later on?

I was told not to use both but need clarification. Google search says yes just small amounts.

Still learning the bahavior of my reservoir at 55 gallons which changed now that I have higher ec, using tap to raise ph doesnt work anymore. Had to add like 7 gallons.

Before at .8ec it was alkaline 6.5ph after adding nutes as they lower the ph.

A few drops either way shouldn't hurt anything.

10 days later I. turned up the light a bit but looks rejecting it and still issues in the nutes. I raised to 1.1ec. Maybe feed more times a day?

I doubt its because it has a 6” hurricane as exaust until I get a fan in few days. No negative air pressure just barely exhange of air. 81F 40rh.

I guess the light isnt that strong let alone how its set right now so idk. Upping ec to 1.2-1.3 and feeding one extra time a day.

Edit added pic of my 1L pots same solution doing good. Mother plants one gal same solution.

I can't make out the par map on that pic, but you should be measuring your runoff and comparing it with your inflow numbers before you start changing your feed schedule when you are having issues.

That said, interveinal chlorosis at the top of the plant without any at the bottom of the plant is typically either an iron def or too high of light. What are your PPFD numbers? In veg, you shouldn't really be going over 550.

What line of nutrients are you using?

I didnt realize it was blury, here it is. Maxibloom the tap ec is .5 and mostly calcium and magnesium. I have light dimmed to about 25%. My phone app measures in lux and was 10k lux last I checked before turning it up a little.

I use RO, but I think with fairly low EC tap, you should just add that number to your EC; in your case, maybe add around half. By day 10, I'm at around 1.1EC using 0EC water. Once again, you should monitor your runoff EC to see if a change is needed.

I mean, if you're feeding at 1.1 and runoff is consistently coming out at .6, then the problem is it either needs a higher EC of nutrients or the fertigating needs to be more evenly distributed across the plant; however, if it's going in at 1.1 and coming out at 1.6, then the problem is you either need to increase the amount of times you fertigate each day or the EC of the nutes needs to be lowered.

So... what are your runoff numbers?

Will check next feeding. What do you mean add around half? Adding what number from where to my ec?

To keep it simple what should my base nutrients be aside from my ec of .5 from tap? Pretty stoned right now bare with me lol.
