Week four of flower and my leaves are turning brown and crispy. I know I have a slight over watering issue, but besides that I don’t know what’s happening to the leaves. Temp never goes over 81F and never below 68. Feeding hasn’t changed. Lights about 14 inches away led 3 600 watt growstar lights. Please help

Inexperienced = I googled your symptoms and came across another roll it up thread, similar looking issues. The last post suggests ”too much potassium” or incorrect ph can lock out nutrients. The solution being to add cal/mag or to apply dolomite lime before potting.

PH is good maybe to much potassium though. I’ll see if adding calmag works thanks!

... Is what I got ...
This is awesome! Two of these I have never seen before. I’m going to look more into the mineral interactions. Do you think mixing nutrients first then adding water would have any adverse affects? Compared to putting the nutrients in after I fill water jug full of water.

As long as the solution is mixed with the water properly either way should be fine. I read somewhere that certain nutrients bind together if they are in contact with each other in large amounts. Can‘t remember what ones or where I read this ... might take some googling. As long as you use up your mixed nutrient solution and don’t let it sit for too long I think this will be avoided.
On a side note it’s good to let your plants ”wake up” before watering, I.e not watering directly after/directly before lights on/off. Most of what I’ve learned is from following experienced growers threads. They’re usually pretty good with q&a.

woke up this morning to realize some something is wrong with a few leafs on 1 on my plants i need help to identify the problem and solve it asap. ill start by describing my setup, im using basic potting soil under 2x viparspectra tc600 in a 120/120 space using foxfarm nuts, temp is between 20-25c humidity is between 60-70% and lights are on 24-0, my feeding schedule for this plants didnt start till week 2. started with just blig bloom 4ml / gl but only had a ltr of the gl week 3 i got bit confused as to what i was doing on Sunday i gave 4ml calmag /gl then on Tues 3ml big bloom 3ml grow 2.5 ml cal mal then Thursday 2ml calmag then sat ph water only then monday 2ml call mag 3ml bigbloom 2 ml grow 1ml bloom then wendesday 2ml cal mg 4ml big bloom 2 ml grow then on Friday 2ml calmag 4 ml bigbloom 2ml grow today i planed on giving ph balanced water. there is only slight damage to the newer leaves and 1 more mature leaf some tips have yellowy browned and started to curl in purple steaks on stems few yellow spots and newer leafs are a bit light in color. all my water is between 6.3 6.7ph just realised the soil is 7.5 could that be the problem purple streaks are more on fan leaf stem but could be coz of lights

So I moved my girls to their new DWC home 3 days ago. Experiencing a few issues.

1. Plants have stopped growing in height but roots are blowing up!
2. The slowed growth seems to be accompanied with downward curling of established fan leaves.
2. The PH of the nutrient solution seems to spike significantly over night. I feel like I should not have to add PH down every day. There must be something I am doing wrong.

Any advice helps.
 
2nd grow ever: 8 weeks into vegetative
-spiderfarm 1000w led
-higrow 600w led
-ff of soil
-ff trio plus: fish emulsion and gringo rasta cal mag
-strain: pineapple express by Amsterdam marijuana seeds

My leaves are drooping on my larger plant! Its starting to concern me. My initial suspicion is that there's too much light. Had been using the higrow 600 w led initially but just installed the sf1000 about 4 days ago (using them both in tandem). Both lights are about 18"-23" from canopy. Anyone got anything? Many thanks friends

*edit i keep my room around degrees 82 f .
Humidity has been a bit low lately but trying to stay around 50 rh now.

Never do that. There's a reason they are in separate bottles. Mix into water one at a time, correct the ph.

I have a 4 month old purple alien which is in week 3 of flower. It’s under a 600W HLG LED. Temps range from 70-87F. Medium if roots organic formula 707 mixed with a little more coco and perlite. I top dress amend monthly. Recently amended with Down to earth 4-4-4 and also DTE seabird guano 0-11-0. Having some slight issues. Maybe P burn? I PH around 5.8-6.3. 5648F7D1-2145-4264-9C68-0C6C74E3BD4E.jpeg

Could this be calcium deficiency?

Yes, it will. The directions on the label almost certainly tell you not to do this, and how to properly mix things.

What happens is that some synthetic nutrients react with others causing "precipitation". In essence, they bind together when mixed, and fall out of suspension of the solution. The nutrients that have precipitated are no longer available for plant uptake.

Take the directions on your nutrient bottles seriously.
