Alright guys, first, hello! first time grower here, and well, it’s been quite the ride! The seedling and veg stage both went really well. Noticed a lot of consistent growth and no noticeable deficiencies. I recently transplanted my girls (LSD & Black Widow) into 5 gal pots from 3 gal pots. I’m using MonthEarth GroundSwell soil and my nutrients are all Roots Organics:
Terp Tea Grow
Terp Tea Bloom
Roots Organics Trinity
Terp Tea Microbe Charge
I’m in week 1, day 3 of flower and they got their first “bloom” feed on Monday. Today I noticed some signs of a deficiency and I’ve done research all day and keep getting different answers. So I’m asking for y’all’s knowledge and any info or advice is welcome!
Recent feed:
1.5 Tbsp Terp tea grow
2 tsp Terp tea bloom
15 ml of trinity
2 tsp of microbe charge.
brewed in a TeaLab brew bag in an open bucket with molasses and worm castings. Brewed for 28 hours. Fed them each 3 liters.
Spider Farmer SF4000 26” from top of canopy at 60% intensity. Temp is 76-78 during the day with 50% humidity and 68-70 at night with 50% humidity. I did have the light hanging about 17” at 80% intensity after having them under a SF1000. So not sure if it is heat stress… I also use unfiltered tap water I let sit out for 1-2 days and I PH after adding nutrients and brewing to 6.3. My tap is very “tappy” to say the least, with my ppm being around 400 without adding anything and PH roughly 8.0. Water temp is about 68-70 when feeding. Any help is welcome! Sorry for only having 1 pic.. timer went off and the girls went to sleep right after I snapped the 1 pic. But this is pretty consistent throughout the top of the canopy mainly on the LSD. (Which stands taller at the moment By about 4-6”) my guess is cal/mag deficiency but both the Terp tea grow and bloom have 1% mag and the grow gas 4% cal and bloom has 8% cal.. haaaalp!

Slow down on the nutes. Let the plants catch up. They don't need flower nutes until they have flowers.

Most definitely, thanks for the tip! I am following the Roots Organic feeding schedule on their website and it recommends “bloom Terp tea” from week 1 of bloom up until week 6. So you’re thinking it’s a nute burn? Not the entire canopy is bad, the leaves are actually perking up as of today, but definitely a lot of yellowing and twisting and some mild brown spots.

100% proof that feeding schedule is bonkers

Initially when looking up the feeding schedule it seemed like you could use every nute they offered and somehow it fit into the schedule. Seemed weird to me too as nute burn is obviously very possible lol. But I wasn’t sure exactly what I was doing or how to identify plant needs so I figured following a nute schedule was my best bet.

Lol hey man, just trying to grow some quality stuff. First run, I suppose I’ll get a better grip as time goes on. You also think it’s a nute burn? Here is an updated pic from about 1 hour ago

Looks like the beginnings of it... or a PH lockout. Could be alot of things. Raise your light a bit (or get a good PAR meter), and flush it, and re-feed with a lower dosage. If you have a mobile nutrient lockout, you'll see it from bottom to top. But burn will start mid to upper mid to upper growth. Only way to figure it out is to flush, re-feed at a lower dose, and watch your new growth.

So it seems most of the yellowing/brown spots and curling is on the top of the canopy. And it’s only on the LSD plant which is taller. So yeah, heat stress makes since to me. I also did give a heavy dosage Though so I will go with the regular phD water. I raised the light to 30” (4” higher) today and kept it at 60 intensity as well.

Give it a go.... can't hurt. Next time they need water/feed, flush it with 3x's the pots volume, and immediately re-feed at a lower dosage.
