Big leaves burned !!

[Pera lepak]

Got this lovely Night queen in soil for 43 day now, had N excess before but with few ph waterings she was fine and now i have new problem, big leaves are yellow and stiff and dry and looks like growth of buds slowed down a bit.

Changed lights few days ago, migro 200 instead of cheap led, they are almost the same wattige, dont know does this have anything with problem.

Thanks.

Feed with a good balanced nutrient veg cycle. It looks like the leaves are taking in a lot of water in an attempt to get more nutrients making them droopy. You are showing signs of various deficiencies so you may have just washed out most of the nutrients in the soil. Now lets talk about PH. Do you know the PH in the root zone? You need a good PH soil probe to check the PH in the root zone. Get a Blue Lab Leap soil probe and meter or an Accurate 8 soil probe or the clone of it. Don't buy cheap ones they just do not work. In the mean time PH your nutrients to 6.3 going in.

@Pera lepak @Mañ'O'Green . I agree that ph should always be checked. Years ago I learned the hard way. It looked like a torch hit the leaves and it went bad really quick. I posted pics years ago if you want to search. It literally happened overnight

I don't know ph of root zone i don't have soil probe, i have just for solution and even that is cheap chinese thing that my local shop got it, so i'll def need to go to agrycolture shop for proper one.

i?ll give it some micro and grow today and i'll keep you informed.


Does run of test helps at all while i get pen?

-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics!

Medium: Soil 70% and perlite 30 %


Feed and supplements used: Advanced nutriens, i started with 1/4 of dose in week two, had N excess and done 3 plain ph watering, had another N excess becouse i stared early with N nutes and another 3 plain waterings, 10 days ago gave her nutes for flower with no N, and soon problem acured, so yday went back to grow nutes.

Water source: tap water watering by hand

Strain and age : Night queen day 46 she strted early to flower in beginig of week four.
