F48 - Fade or Deficiency

subtechny · Oct 11, 2021

Hello,

My plant is 48 days into flowering, about 60 days veg. Unknown bagseed. I was feeding it FFtrio then was almost out and decided to switch since it was expensive on amazon and unavailable near me. So I found GH FloraNova Bloom and gave it a go. Looked fine at first but now I got these red yellow leaves.

Not sure if it's nitrogen deficiency or not. Cal mag? Or just normal fade before harvest

Trichomes looking like this yesterday.

Ordered an apera yesterday.

Was testing with dye test and pH strips before.

Thanks for this quick response.

So I recently watered it. Probably pH all wrong. When I get my apera meter and bennies today.. do I water again with bennies?

I'm using fabric pots

Don’t over water. Let soils dry. Always let soil dry before next water

If you switched nutrient line maybe you kept your old schedule? So you give them too much or too little? The problem could stem from the PH too. I would try to flush them with 6.5 to 6.8 water(If growing in peat moss wich is naturally acidic, so no need to have an ultra low PH or it could cause low PH problems in your soil) and then directly give them the reccomended schedule written on the bottle

Look overwatered too. let them dry for real to the point they weight almost nothing and then water

No real science to back it up but just like stretch consumes N, flower consumes P.But thats if everything else is in check,pH watering etc..Most people switch to flower nutes to early,heavy on PK when plants need/want N. Imbalance starts and the tail chasing begins.

This I know. Just didn't want bad ph'd water in the soil. I appreciate the advice.

She was doing well in the beginning. It's later in bloom that I switched to FloraNova. I'm definitely double checking everything. She was rocking before I switched from FFtrio to just flora nova. Thanks for this information.

I changed the feed according to the bottle since this line from General Hydroponics does everything in one bottle. A bottle for grow and one for bloom.. I'm on the bloom cycle and I'm dosing her 2 tsp per gal.. she will drink the whole thing with about 20% runoff.

I think I will let her dry and double check the pH for the next watering. Thanks

Plant looks pretty good really,no burnt up leaves or clawing.Feeding to runoff is a good move,kick out the old to make room for the new lol.

Don't forget that if you're growing in a peat moss medium it is naturally acidic, so if you lower your ph too much you will get an ultra low PH runoff from your soil. Save some PH down and try not to go any lower than 6.6 if you are growing in a peat moss medium. That's an advice that served me well.. After trial and error

Growing in FFOF.. just got recharge for the soil .. im sure it needs it since I never gave it bennies..

I aim for 6.2-6.8 pH going in. Let's say I check runoff.. how far off should pH be then?

Fox farm is pre buffered a 6.3 I think so that range seems fine. But being a promix grower, I would't go lower than 6.6

Maybe use a narrower range of PH like between 6.3 and 6.7 to prevent PH fluctuations?

So the pH that runoff gives should be relatively the same as what you put in.. or does my soil bring my pH down. So put in 6.8?

As of my experience, in soil, wich contain peat moss, the PH of the runoff is always lower than the PH of the water you give to the plants, And I can also say that the PH directly in the soil is lower after testing it myself with my bluelab soil pen

Gift.weed.exe · Oct 12, 2021

All I'm saying is don't go overboard with the acid and save yourself some down(or it could cause problems, particularly in soil). 6.6 is a low enough PH for me

myke · Oct 12, 2021

If salt is built up runoff ph will be low.I run promix with dry nutes and ewc.Water straight from my tap @7.2pH.No problems.

You think? I think it’s more to do with switching up nutes.

@OP what are the ratios of the feeds? Before and now?

If the N is lower on the new feed there’s ur issue.

Dont Chase your tail with pH..
