New Grower Think different veg problems

[grosfrag]

Alright guys, my think differents are at week 4 today, im getting some yellowing some leaves, mainly lower large fan leaves, They had 1 feeding at week 3 and 2 days of .3ml of bio grow / 2l. Watered today, ph in 6.8, ph out 6.4. Very small rust spots in the veins and over all looking a bit limp.

They are in canna terra soil with 40% pertile.

Any guesses, im edging towards more feed as someone said these are heavy feeders?

But not wanting to OD them they had just water , new growth is fine but lower leafs suffer

A picture would be helpful.It's normal for a few leaves to turn yellow on the bottom of the plant,just pick them off.What nutes are you using?If there gen organics I would up the dose to 5ml per gal of bio grow.

Aloha, your problem could be two things number one being lack of cal/mag and pro-tekt or number two your micro nute is not compatible with hard-water if your running of straight tap water I'd recommend micro nute specifically engineered for hard-water and vise-verse if your on R.O or D.S then there is a lot of micro nutes designed to blend smooth with out the worry of having chlorine dissipate the micro minerals. All in all you gonna want to get your paws on some pro-tekt use as a foliage spray with sm-90 or diluted h202 this will help with the fungus growth and leaf rot add to you feed bucket 1/4 per 1 gal this will help build immunity towards drought and heat stress of any kind e.t say if when you water your plant and after a few minutes you noticed she looks kind of droopy pro-tekt will prevent that wilting and keep her veins strong and free- flowing good luck to you sir.
Aloha.
